The Cal-look Lounge

As of this week Angleflow heads are available again,they come bare with no head stud holes,seats or guides so what stud pattern,what valve size etc is totally up to you :)  They are cut for 94mm cylinders,but are really set up for 101.6mm[4inch]bore or bigger :o

I recieved my bare heads this week,they are available through Jeff Denham[ugly duckling] who I got mine from and his business partner Tim[58vw] both on here,also Bugpack have a few sets,the pics show what they are like :)

cheers richie,uk

is there an exhaust system for this richie or is that a made system as well?

They still look nice , and are as bare as a headbuilder likes heads  :)
I think only Buckpack sells them !?

The exaust system must be custum build , or you can modify any other with only a little work . I did some for a customer some years ago

Udo

Udo,this was a project between 3 different parties i believe,bugpack was just the central figure having access to the molds,the other parties invested heavily in this,The delivery to Jeff I saw was 40 pairs I think.

And there will be a header available as well :)
cheers richie,uk

you want a header built. not a problem i like building those more than i like doing heads. im going to build two of each size the smallest NA/ 1/3/4 1/7/8 2in and so on. turbo header not a problem.or you can build it your self if you have a TIG/mig and a BRAIN and you know how to use them well you shouldent have a problem . thanks richey for the posting the news ;). aint them there heads perrty.UD

Hi Jeff, As they are what size chamber do they have?

Thanks
David

Another question jeff what is the cylinder head tin fit like, the bits that go out to the shelfs, do you have any engine bay pics of your set up?

COOOOOOOOOOL Heads - but what about inlet manifolds  ???

inlets not a problem ida only at that momment. you could modify a set of idfs super flows to fit if you had to. UD.

 ;)

that set up looks the dogs ;)

Hmmmmm now I'm getting some ideas for "PROJECT 66" ;) :)

It is good to see that there are people that keep those nice heads alive  :)

Udo

Good to see these back on the scene.

Stock guide spacing?

What size plug?

hello Jhon. not stock guide center lines. 12mm 3/4.   UD.

That's one small step for Jeff, one giant leap in H.P.

Very!  8)


Might be overkill for a 'Mouse' motor? :P  ;D

 ;D Very nice

How much are they Jeff? ;D

ha ha - I was thinking of them for the "second engine" The 2180 with a Roller crank :o :)

i can feel a purchase coming on!

Can I see some more pictures of the header? And how big is it? I used angle flows on my old 2386 with a heavily modified Berg 2" header. It took quite a lot of work to get it to fit under the rear apron on my 65. I did not have a removable rear apron. From the picture above it looks like the header is curved quite a lot.

the header we built for my 58 fit quite nice, and i do not have a removable apron either ( well i do now for all the different motor combinations we will be testing) and it was a modified 1-7/8 header. i will try and post i picture later. thanks, Tim

hello beetlebug. here are a few pic on the original 3066cc 1/3/4 pipe i had to make the bends tight due to the fiat body figure i was trying not to cut the body so i had to move the pipeing as close to the engine as possible. it still made ok power. engnof to make my old blue 63 beetle go 7.56 ET 1/8 at 92mph 2016lbs all on 9.8/1 comp and 91oct and i drove it to the track and back home. it was a little corked up but man it had some sweet torqe. UD. 

just makin a few chiperooneys. im utilizing and maximizing the flange and runners without welding involed. there is a serious amount acerige in them there runners all for the better for the next monster from hell .valve size will be 54x40. now the manifold will be a different story.UD

D  EX ive had good luck with it in the past it will probebly flow too good.  UD.

looking very nice......can i pick them up tomorrow? ;D

WOW fantastic to see these heads available! Will you be leaving the heads blank, or will you eventually have them drilled to a head bolt pattern? I like the idea of the blank heads so you can fit them to your head stud combo!

Rob.

hello rob. we will leave them blank unless you want them drilled by us then we can do that and anything else to the heads not a problem. UD.

hey 58vw do i look like a cnc machine  ;) some times i wish i had one. i gusse one of these days. UD.

Jeff, those ports look amazing!  I know you like to see heads "huff and puff'n", what kind of cam are you planning to run with those bad boys?!?!? :o

What car will these go in?

David

hey david. roller cam and rockers in the 700+ lift range. remember this guy david not the fat one thats the car it will go in. UD.

mmmnnn  cheese samich ;)

Hi Jeff,
          Can you let go any of the details on the roller cam motor? What kind of rockers will you be running and will you be using the stock 2 stud rocker system or will you be beefing it up?
Were you able to cc one of the angle port chambers?

Regards
David Gouk

yea farmer to many of them there grilled cheese samiches but they taste so darn good.UD

yes david. 63cc thats with no valve job and no shaping of the chamber. i flycut the one chamber down today 190 thou it went down to 36cc but cant go down any farther im in to the plug hole. unless i relocate. UD.

it will be the v8 jessel rockers. the rocker blocks will have to go by by  :'(. UD

thats funny jeff.....hate to tell but im fatter than u!!gonna need to get back to the gym so i dont weigh down the car..kinda like a boat anchor ;D

your fine we need the ballest. here is a nother shot of the completed 1 hole. need to get on the manifold so i can do some flow testing next week. we shall see. UD.

very cool dremel work there!!! what big holes are that!!!

Awesome work UD!

just a littel weld on the manifolds.UD.

Dean would be proud..  ;)

indeed

i feel like a dog waiting to get a bone!! lookin good mr. denham :P

thanks for the compliments guys. im tryn. cant wait to put them on a fresh engine and this time with a little pop behind it.UD.

Real pop comes in bottles- blue bottles to be exact,  :P

I had the chance to look at these heads in person yesterday...Let's just say the pictures don't do them justice. Jeff has always been known for doing good work, but the work on these are absolutely amazing. Keep up the great work Jeff.

thats the next engine steve...maybe in a little black car that needs to be dusted off :-X                                                         

hairdryer anyone??    :D  Looking good jeff :)

cheers richie,uk

Objects of desire. Uber cool!  8)

What do you need that for, don't you have your alice clip?

yooo hoooo Hairdryers  ;) :) just kidding guys  :)

Gotta style it first :D

Anyway off to the track now,

cheers richie,uk 

heres a few more if im boring you guys just let me know. holes are drilled on one match port is all in all done. just in the proscess of triming the blank int valve to fit the seat. i guess it will see the flow bench next week now had to pay the rent this week so my hands were tied even though i wanted to work on this stuff 24-7 oh well. UD.

Work of art UD! :o

hey......why u watchin cheers. ;D ;D

amazing work Jeff. I think my car needs a bigger motor, and a set of these.  You think?

im back guys hopfuly not to bore you. here is some figures these are all truthful figures and the head is flowed at a conservitive 25inches up to 740 lift on the intake. still room for improvement on both int and ex. chamber is still tight on top and ex will pick up with bigger tube. not bad for a head that i dident weld what so ever exsept intake manifold. 1cfm away from 3 hundee dam i wanted to see the big three i gusse if we converted it over to 28inches we would be seeing 317cfm but i want to keep it real.also i just wanted to say thanks to mike at performance tech for doing the test for me. UD.

 if some of you dont under stand the flow chart on the big end on the intake sides reads at 740 lift 299cfm and 183cfm ex at 650lift.hers a picture of the 43cc street chamber with the valves 54mm 7mm stem int and 40mm 8mm stem ex. UD.

Yup, that'll work.


 :o

back with some more. wasent sastified and still am not but will let the intake ride for now. ex im going to change slightly not the shape of  it self but the pocket area. well we hit the 300+ mark. again at 25inches unshrowed chamber and flycut another .060 so that makes a total of 250 flycut and a 38cc chamber now 300cfm at 700 lift 304 cfm at 740 lift int at 28 inches would convert to 322cfm but like i said before were keepen it real.  194cfm at 650 lift ex 64.9% still sorta low on the persentage ex side so im going to play with that some more.well there it is for now the head is deffenetly a true contender in the NA ACVW world for kickin some serious ASS 300+ HP styel i dident have any doupts that it would i am very proud and dedicated to take on the task and cant wait to get ahold of the steering wheel and the GO pedal.   hers a picture of the 38cc chamber and the flow sheet. again thanks mike for flowen the head.  UD.   

very very nice work. cant wait for my set to be done...

Handled.
I have a set being ported right now to replace these -

Hey buddy,welcome to the lounge-nice picture.. ;D

how long to dry its hair with that kind of hairdry  ??? ???................................................................ ;D ;D ;D ;D ;D ;D
rgd
fabs

Jeff,
Absolute genius work! I'm amazed.
A true artisan.

Now ... when will mine be on the bench??? ;)
Get some rest, it looks like you need it!

Take care,
Tom

hey tom..better get in line quick....once that test head is done and jeff is happy, he already has 5 or 6 sets to do..but he loves it so keep it coming

I thought I was already IN line!
Did somebody take cuts?!

By the looks of these, Jeff must be absolutely bored to tears with the set he's working for me right now, and they're going to be pretty cool!
I know he can do them in his sleep though. :D

Jeff, I'll get those flow numbers to ya tomorrow ...

Tom

ya tom...that tim guy and that richie guy...personally i would call and complain ;D ;D













just kidding...didnt you order two sets of angle flows?

YES I DID! >:(
I'm callin!


 ;) ;D ;D ;D


It's all good. I've got time ... Jeff's such a great guy, I don't mind waiting for his work. I know it will be right the first time.

Are mine done then????????? :) ;)  Both sets?? :o

cheers richie,uk

Hi guys, do you think he can do up a set of manifolds for those heads to run dual progressives?

I thinkby the looks of those ports they more need more on the order of QUAD progressives! :o
But I'm sure if you incorporate a SVDA distributor the mileage will be excellent.

 ;)

im sure you guys are YAAAING by now hers a few more pictures and another flow sheet. im gona go back to the bench one more time for the 2.200 int and 1.600 ex side then i will move to other side and do a 50x41 fluff and buff or get carride away like i usaly do. as of right now its 323cfm at 800 lift at 25in still a 58mm manifold opening. UD.

Thanks so much for sharing those pics and flow sheets Jeff, great stuff.
What seat throat do you go for normally?

hers the red hot 56mm intakes. i know its should be cool blue but no blue light. UD.

I bet you could make almost a hundred horsepower with those! Huh?

At your .700" number...

54mm Valve =  3.55" Sq.  at   288 CFM  / 3.55 = 81.12 CFM of flow per Sq in. of valve area

56mm Valve =  3.81" Sq.  at  306 CFM  / 3.81 = 80.31 CFM of flow per Sq in. of valve area


For comparison a decent 42mm T1 head Flowing 200 CFM at .650 lift

42mm Valve = 2.14 " Sq.  at  200CFM   / 2.14 =  93.45 CFM of flow per Sq. inch of valve area

K-Roc,

   


and your point or observance is?

hey thanks you guys for all the compliments. and for the ones that dont think that it is up to your 106.7 standards because ya know what i know what i have done for this hobby which is alot more than some LA based radio staion. i will say again im not done with the head i thought when i started this project i would creep up on the flow and show you a progress flow charts and progress pictures also did i tell you i dont get paid for this kind of thing so i have to draw the line and move on to paying jobs my payment is seeing progress. im not ashamed nor imbarassed what so ever. oh and buy the way not to be mean i am aware what a desent set of 42x37s lowwww comp and high  work like i have  just a fewwww sets around this globe that ime very proude of like about 20yrs worth. take care yall.   ;) UD.

I love you Jeff! Maybe any decenters could DRIVE their rig out to Vegas from OC along side Jeff and race him at the track . Anyone ?

Can I put some money on UD to win? All motor, like for like road mileage, (at the same time of day), one pass, heads-up.

The Radio, ain't like it use to be , epscically when you get all the members of the BAND, on here trying to put some kind of new tune together,but can only come up with same tune every time!!!

 

Darren, So far I have my new Component Development heads flowing 350 cfm at .800 lift @25" with a 53mm valve. This comes out to 104.47 cfm of flow per sq. inch. How does this compare with what the V8 guys are doing?      Pat Downs

thanks for sharing those numbers that anybody can type on a computer....i only see Jeff putting his balls on the table and sharing numbers from actual flow sheets from an unbiased source....i also do not see him stealing other peoples threads and basically bashing other peoples work...but if that is how you want to be then maybe you should start your own thread to discuss your heads......this just reminds that no good deed goes unpunished.






oh and by the way bring your real street car (NA) that can make a 40 mile plus drive and YOUGOTHEADUP!!!

Sorry dude but I don't have to make up flow numbers. If you want some pics of my heads on the bench showing the flowcom at 350cfm @25" send me your email address. Unbiased source? I have nothing to do with the CD head. Our company has it's own line of heads. I use the CD head because the biggest valve I can get in the Comp Elim is a 50mm x 40mm. Just to let you know, I have pushed the CE head to over 300 cfm at .750 lift with a 50mm intake. I plan on running my car in the Pro Stock Nationals in 09. This is why the move to the Component Development head. But, so far the Comp Elim has gone 10.07 at 137mph in a NA 1550lb car.  I was not trying to take anything from Jeff and the angle flow head. The angle flow has been around forever and is a great cylinder head. Bashing, I don't think so. I'm sure you know, there are porters getting 315-320 cfm from a 50mm valve on an autocraft head. I think Darren was pointing out that the angle flow head Jeff is working on has room left in it. Jeff said the same thing and I am sure he will improve on it.  Relax a little can't we just be friends ;D BTW, you seem a liitle old to be talking the yougotheadup, I thought that was for little kids.

right on..like your response..

oh and the headup comment....keeps the mind young...so ill take the little kid comment in stride ;D

and good luck in the prostock nationals next year! Tim Sholl

Sounds great Pat. Is the intake port still the same size as the last time we talked or did you open it up a little more?  I am guessing that is without manifold but with a clay raduis of some kind on the port? ( if it's with a manifold your my new hero )

And your right... I was merely pointing out that there was a bunch more room for Jeff in that port.  I think with that size of valve it will be hard to get the number up there without welding now, as the choke point will be too far up the port. ( perhaps my wording could have been a little different to protect the sensitive types) But these guys felt the need to jump all over it and bash my nickname etc...

The port is still the same. I actually picked up a few cfm with the manifold. With clay, the port flows 345cfm. The manifold must be directing the air into the port better.

sorry if i affended you in any way. i usaly have the utmost respect for most hand taylord head guys like your self D.K  i think if the tables wern turned that you would have acked in the same fashion if i would have come on your street elimnator thread but i know better not to i wouldent have done it. i do apresate the constructive critasisum thou and i thank you for that. as for the AF head i am trying too utilize the the chamber space that i have wich is alot i dident want the same old 50mm 0r 52 or 53 i want too see 56 work and i will 2.200 now thats some space and if i can make it work it will be worth it to me anyway. i wont qwit until i do so maybe i will have to weld on the head or maybe i wont will see. take care yall. UD.

It's all cool Jeff, and thanks, as I said in my previous post I could have worded my statment a little better, ( sorry bout that)

My biggest concern for the 56mm Valve now would be if there is enough meat down below the valve seat to get a big enough bowl and short turn in there.

Thanks

K-Roc,

Just out of curiosity UD, in the intake line up theres a % column, one in the ex. then the one which gives the E/I ratio - what do the ones in the intake and exhaust actually represent /what are they a percentage of? Apologies if this is a dumb ass question...

hello kafer boy. are you talking about flow sheet #4 the numbers down on the far right if i understand you right those are the numbers what it would be if we would have flowed the head at 28INCHES of flow 342cfm at 800 lift. but since we did not we will see the lower #s 323 cfm at 800 lift at 25 INCHES. hope that anwsers your quistion and also if i may point somthing out i have never flowed this head and any other ACVW head with out installing the INTAKE manifold first i would be curiose to see what it would do with out it but what would that prove. nothing to me. flow it like it was meant to run on the engine the only thing were missing is the fuel dumping devises.  UD.

Superflow flow benches have a selection of flow orifices, ranging from small to large. Each orifice is rated at a particular flow cfm, based on the depression chosen for the test (25" H2O in this case, as seen on the vertical manometer).

When flowing a head you typically start at low lift eg .050" and work your way up in .050" increments to max lift and beyond. At lower lift you opt for a small-ish orifice, the idea being to choose an orifice that flows just a little more than the capability of the head at that particular lift. You'll notice from the flow sheet the percentages you mention increase up to a point where the next largest orifice is chosen, at which stage the percentage drops and then increases again with higher lifts.

Superflow's inclined manometer shows what percentage of flow you have through the port compared to the orifice unobstructed. Eg if orifice no2 flows 100cfm by itself and with the head in place the inclined manometer is reading 85%, flow for that particular lift increment is 85cfm (100 x 0.85). As you increase lift, the port will reach a point where it flows more than the 100cfm orifice is capable of so you step up to no3 and calculate your flow as percentage of that, and so on.....

To summarise, the % figures you refer to aren't directly related to the head itself, more to do with the way flow is calculated as a result of the various orifice sizes the Superflow design uses and this info is needed in order to calculate the cfm figures we're all interested in. Taking the various percentages and cfm numbers from the posted photos of the flow sheets allows you to calculate the 100% figure for the orifices (labelled 'Range' on the flow sheet) used for the test.

More modern benches do all this electronically and save the pencil, paper and calculator work. Digital add-ons are also available to digitise older SuperFlows but although the older method takes longer, the end results should come out the same.

Not sure if I made things any clearer?   ;)

thanks for that john. UD.

Thanks John/Jeff. All added to my memory banks!!

It will always flow a bit more without the manifold (and with clay formed around the opening), but that info is pretty meaningless since you can't run an engine without a manifold.  I'm sure many guys who do flow heads w/o the manifold, do it just because they haven't ported it yet.
But that brings up an interesting point.  When you look at the advertisements or postings of flow numbers, do they include the manifold or not?

Not to mention a restrictive IDA on top of everything...
Awesome work UD!!

But tell me were lies the gain in these heads compared to some other Superflow relative?
With less of an angle on the exhaust it seems to make sense to the untrained eye, but what about the exhaust? You would have to make a much sharper turn to get back to "square one"? Is it more "ok" to turn sharply when you have some distance form the exhaust valve... or isn't this the trick about these heads at all?

In my humble opinion, THAT is how heads should be flowed! Everything from the velocity stack to the valve.

Looking pretty sturdy, UD ;)

How do you create the standard then?  What venturis?  What stacks?  What about the guy running big EFI throttle bodies?
Because of the vast variables, it isn't much value to include a carb.

I wonder about the header too. I guess if the bend from ports (primary) are large radius, then it would improve scavenging? Then we need to talk about length...   ::)

And cross section of exhaust port shape? Isn't the "D" shape the "magic trick".....does that still work with these angled ports.

Sorry UD, we are snaking all of your speed secrets!!! Awesome work, and we are all learning a lot from your hard work.

keep up great work, and thanks for sharing

im sure that alot have there different opinuon on the ex port design. this is my thought. im thinking the port design would be very promising realving heat out of the head faster than the deep long radius type heads and also not exposing the valve stem as much there for not bending ex valves stems in turbo apps yes you need heat in turbo apps but not to the pounit were you are melting ex stems  as far as flowing better than conventinal stuff all i can say is im working on it. i have always been conservitive on my port size on the ex side. whats nice about the flange on the angle flow is that the studs are spread alot farther than oem stud location wich makes it nice when installing hardware. some people have a hard time relating to the angle port due to having to custom build a header for it. well its not a big deal nothing that cant be fabed up. and whats cool about the port design is that it dosent look the norm who the heck wants that i surely dont.just my two bits if it means anything to anybody engofe rambeling for now.  UD.

steped up some on the manifold. will see on the numbers. now its a 2.450 inlet and 1 1/2 taller. UD

'So, yeah, I decided to just make those manifolds a bit taller, you know, why not?'

:D :D I wis I had that kinda talent UD, looks awesome.

talent , understanding and determination !!

looks like a toilet bowl......and i meant that in a good way ;D

heres a new flow sheet as of 7/2/08 still no weld what so ever on head casting obvius weld of coarse on manifold chamber has 34.6cc. port on cly head casting has stayed the same since original flow sheet #1 wich was 299 at 740lift. now were at 323cfm at 25in like always at 750lift and 331cfm at 800. and solid 200+cfm#s at 300lift to 600lift should i keep going naw ive proved my point on the intake side. time to up my exhast. as of right now the intake on paper has the potential to make NA360hp at 13.5 comp and above. also again head was flowed with manifold like always now at 62mm entry and spark plug like always never to give false #s. am i proud of the #s (darn tooten!!) UD.

Awesome work Jeff!   I want to hear this engine rumble 8)     Have a cold one dude, you deserve it ;)

Wow. Nothing else to say really. ;D

Great work Jeff as always the only thing is you may need to put four more holes in it.


Or you are not going to be able bolt it down. :D

 ;D ;D ;D ;D ;D ;D ;D ;D

Very impressive. I love to see the industry charging forward! UD I bet you have aluminum shavings all over your kitchen. My wife would be pissed.  ;D

hey richie.....you sure you still want that turbo..... ;D

oh tim leave him alone. richie likes leaving contrails in the english air with his conair :P. UD.

IMO the A/F head is the best turbo head there is.

Also, I dont see these heads being used on anything smaller than a 4" bore head stud pattern unless you use the ARPM 3 liter head pattern.

ya i was just razzin richie...since i know nothing about turbos and im an na guy i leave that stuff to the experts like you and richie and all the other fast guys out there.

and as far as the 4" bore stuff on those heads...thats exactly what we are pushing for, make it more readily available for those he may want to build a 4" engine. ;D

well....happy 4th to everybody!! im off to disneyland :'(

wasser boxer pattern works great on these castings.heres when i used to have to weld them up. well not no more thank god. UD.

Art.

oohh ahh  ohhh ahhh. thers gold in them there heads.ok berilium copper close enoghf. 1.650ex/2.150int.UD.

 :D :D

Hi jeff :) nice to see you are still on them :)

cheers richie

Those are some REAL good flow numbers now!

Now digitize them and go into production...

Why bother buying intake manifolds? 2 flanges, create the runners with weld...

In all seriousness, Really nice work.

thanks guys. youl see some better #s ive got a few more trickes up my sleeve. UD.

Nice work 8)

Would these work for a street motor though or just for the drags?
Cheers,
Kev

wow I love see UD word this heads lol big nice valve !!
great job
liou

Kev


I think they have been proven on the street :)

Jeffs own car was driven all over with those heads on his 3litre in his blue bug,then on the real street cruise from LA to Las Vegas only on pump gas and they travelled about 75/80 alot of the way where traffic conditions would allow,then raced them,then drove back home again :D

cheers richie

anyone know what the heads flowed stock?

WOW! jeff nice work. the only complaint I've heard is that those dog's need a ride with those new heads. Keep up the good work and I hope everythings going good.

I was thinking about this today
and instead of comparing flow to surface area of the valve
SA(V)= D(pie)
compare flow to the surface area taht air is cactually flowing through
wich would be teh circumfrence of teh valve times liift
SA(F) = (Rsquared)(pie)(lift)
So the 54  gives 2.48" SA or 115CFM/"
the 56 gives 2.67" SA or  114CFM/"
lastly the 42 gives 1.39" SA or 143 CFM
but for my valve surface area im getting
54=6.67"s not 3.55
56=6.92"s not 3.81
and 42=5.19 not 2.14
maybe my converzion is wron im using
1 millimeter = 0.0393700787 inches
taking the MM(0.0393700787)(pie)=SA

Have you been drinking energy drinks Austin?

Not sure what you are getting at completely, but I have an idea.

It may be more clear if you use different terms to describe what you men.

Valve AREA is (pi)x (radiusxradius), and really the valve throat area is relevant if that is the minimum cross section in the port.
(not always at the valve seat throat ;))

Also relevant is the CURTAIN AREA, which is the VALVE CIRCUMFERENCE multiplyed by lift.
Circumference is = (pi) x diameter

Both these calculations, and the actual flow numbers are handy when comparing various valves and their flow numbers at different lifts.

Guys like Jeff, Darren K, Pat D and the hell-guys from Heads-Up! know what numbers are representative from their vast experience,
so they can compare apples with apples.

Interestingly a 4 valve chamber has massive curtain area, and large low lift flow numbers without the large cross section.
But this may not be an advantage as you may first think.
Although the japanese designers seem to have made the most of both low and high lift flow numbers in some production engines.
Normally they use smaller duration to avoid too muc low lift flow, too early....typical of 4-valve, or any large-curtain-area/excessive low lift flow combos.
     

Sorry about the verbal diarrhea.

thats what i meant
wouldnt it be better to compare flow to curtain area instead of valve area?

Dave, I have been following your progress on the aussieveedubbers with your new head combo, very nice, always good to start with a clean sheet of paper. I am doing the same thing with a pair of comp "e" heads.
It will be very interesting to see what happens at the dyno. ;)

some more head candy.

this will be the round int/ex street/race port. valve size is 50x42 the ex seat will except a 40 but wanted to see what it would flow with the bigger 42 will see this week. you turbo guys may like this set up. again there is no weld what so ever on the head casting and the manifold this time as well. the rnd int is smige bigger than the original port just slitely warmed over  :P.  UD

more to come. when we head over to the over size vacume cleaner. enjoy. UD.

what about rocker shaft support for those high lift motors ? will there be extra support ?

Cheers

hey wont the engine run funny with the different ports like that? ;) ;D

hey rob. when i do the crower conversion rocker set up there will be plenty of support. as far as your standard rocker set up the rocker blocks on these heads are alot bigger than the early 80s style angle flows and in my opinuon shoudent be a problem. UD.

is that a CNC mill?

Nice!

naw austin. are you gonna get one for me for christmas. come on be a pal.  :).  UD.

u might be able to buy mine if u can come up with the right amount of $$$
need a  5 Axis

 ;D

Hello Jeff, man there looking good, been following this thread witha lot of interest.

I've done the Crower rocker Conversion on my motor and i must say its great! even running the 700lb springs they just seam so stable.

Keep up the good work!!!

Woper says Hi

holy crap batman :o

that looks like a CNC to me
A D^MN 5 AXIS CNC at that
WITH A ATC!!!!

Looks like a Haas VF-0 or VF-1. I've got 9 years on these machines.

how much would a CNC set be?

i have to say these manifolds blend very nicely to the head ( smooth transition) not like  other brand heads that i have worked on. the angle flowes are deffenetly match port freindly.UD

thoght i would keeper small with the 51.5 inlet. compared to the other side man thats a dinkey hole. UD.

Where would you put the studs? Also, the valves would be VERY shrouded and the valve spacing is for a 4"+ bore.

hello marty. my original set of A flows on the jhon deer were 94 bore before i welded the holes up and made them big bore. and the guide centers are way tighter. i dont see why a 51x38 would not fit in the 94 bore A flow. dont know if the 94 bore core box is the same one for the big bore. both the rnd port styel 94 bore and the 101 heads look idenicle. except for stud location and guide centers. yes it would be a tight fit with the bigger valves. UD. 

why not cast some big azzed manifolds to go with those bad boys? As long as you are pouring aluminum...

Hi Jeff,
          When you did your flow testing, Did you do any velocity checks? If so, do you mind sharing? thanks David.

I have some originals too and it seems like it would be fine. The new style intake ports are indeed in the way now - I have tried both the 94mm stud pattern as well as the 96.7 pattern.

94mm Bore Models available soon.  :)

Beautiful work, Jeff.
The CNC proposal is very incouraging! WOW, that would save you an awful lot of time ... you can sit on the couch and eat Cheetos while 10 sets get thru by the end of the day!
OK, maybe not 10 sets, but I can eat a whole lot of Cheetos thru the course of a day ... I just tell everyone is orange Dykem on my fingertips ;D, who's to know.

Did I just write that out loud? ;)

Can't wait to see the flow numbers from the round ports!
So mine are still way up close to the front of the line, right?

NO CUTS, guys!!!

Texas tom.....

we regret to inform you that due to recent events your heads have been sold to pay for the CNC start up so that we may facilitate the new orders coming in, however you will be first in line next time......



















JK ;D ;D

Don't make me come out there ...  >:(

Aw hell, I'll take another set ....  :o

That's OK, Jeff assures me the stock casting welded units on the way to me now will flow the same as the AFs, that is as long as I can get the lift up over 1.200" and run it in a vacuum.

Heck, I work there and I didn't know that >:(

i guess its on a need to know basis...  :o ;D

that bulletin must have been during your nap time.

cool let the 94 bore ones come. just a few more one of a kind made in the good old USA type 1 ACVW cly heads to flood the market just a bit. UD
.

So that's what you do! You told me you made the coffee! ;) :D

 ::)

Making coffee is a big job; someone there at least needs to know the difference between decaffeinated and regular ;D

It's called a power nap, you earn one of these when you are the one working during the day…

Can't be that much power, how many stages of nitrous does it have?






BTW, do you need your lawn mowed?  :o

I can understand – that kinda stuff is way past Rick's comprehension. :D

The only thing funny here Mr Ha Ha Ha, is you better have a car capable of blowing my cars doors off in Vegas or the money to pay off all of the bets you have made, instead of acting like mister funny guy on all of the forums, you should be out collecting cans & mowing lawns for money :D :D :D

i dont need a car fast enough to blow ur doors off
ull probably be napping at the tree

Just have your money their!

Sorry Austin, I'm with Dominick here- he'll be finished with his nap and at the thousand foot mark before yours finishes booting up- Mike and I will be waiting at the top end for our $$$.


Seriously though, this is getting off topic- let's move this feud to a new thread.  I can't wait to see more pictures and progress of the new angleflows.

I'm done with this post, it's about the A/F heads  not about dumb ass stupid talk.

How soon?
I need them YESTERDAY.   :'(

Any more progress on the heads UD? Any updates? Your head work is awesome. Im interested in the difference between the big port and the small port. Is the smaller port better for drivability? And is the big port better for max power?

Thanks
Gabe

here ya go. sorry it took me so long to flow the other side. never enghouf time in the day. im not done yet with the street port but this is a good start. big chamber 60cc+ relitive small manifold (NO WELD) and only flowing to 600 lift to keep it STREET REAL. as it stands right now on low comp 9.5 and 91 oct NA 240+hp is possible. this is a 50X42.  int is 241cfm at 600 and ex is 184 cfm at 600. defenetly resepectible street cfm. heres some pictures. UD.

again a true 25in flow test.

more .

more .

i will be back with some more. with around 270 and some change would be good. WITH NO WELD. also thanks again to mike at performace tech for flowing the head. UD.

hey texas tom here is a good example of the 94 bore weld up job if ya know what i mean there vern  ;) think they will flow over the 331mark i would hope so after al that. UD.

stud holes. garenteed to have slight skin canser after this job. UD.

here is one that lost a few ponys goin thrue the lights at the dale. easy fix. one of these days.

Those look like the previous generation.
What size valve?

my original set. 52x38 103 bore. originaly the big rnd port then redused them down to the small sq. INT flowed 250 at 650. the engine made on the chassie dyno 215hp and 215tq@ 5900. 91 oct 10.2.1.  soon to THUNDER!!once again.UD.

marty. those are the late earlys round ports that i slityly modifidy 3 years ago but never got a chance to finish. i originaly wanted to stuff 55x40 in them i will have to measure to see if that can be done. im pretty sure thats not a problem. the NA prostock REV IT TO THE MOON port  ;D. UD.

man what did u do to that poor head...looks like it got in a fight... ;D

yea it got in a fight with a lead foot hockey player  :P ;). UD.

well stitch them up and get him back in the game.....no crying over a little owe ;D

Any chance we'll see any 4" angleflos goin down the track in Vegas next month ???? :o

I plan on being there.

Hey tom....no i will not be there...to many things going on for me. but the 4inbore street car will be back out soon, maybe by drag day we will see. although it appears Marty will be there i just read on his post...dont know what he is bringing but im sure it will be good.

Are you going? i seen a pretty set of heads the other day heading for texas soon, what are those going on? ;D

Yeah Marty, what cha got up your sleeve? Are you bringing a car?

Tim, yep, those "little heads", as Jeff refers to them now, are going on my new street motor. The way he said it, I should maybe save them for my lawnmower! Well, even though the intakes are under 50mm, they'll still get me to town! FOR NOW!!! ;D

Jeff, Thanks for posting those recent pics! Looks like lotsa work to convert to 4" from 94. I think I leave mine as is since they're already done and such. We'll see ... I may sell them instead???
 ... Marty? ... I'll get those numbers today, I hope.

TexasTom

another 4in case out the door.sorry to get off track on the heads. will soon have some new things to show and tell.UD.

Holy Cow !

Hard!

Nice work, Jeff!
What kind of cutting head do you use to face the case for the barrels? ... nice finish.

And how do you locate the stud loactions on such an odd surface?

ancient chinese secret ;D

Endmill

here is one im saving for a rainy day. a machinest nightmare but deffenetly a chalenge.this will be my next pump gas street engine. one of these years. some of you know whos brand case it is. i wont reveail the name. defenetly i feel a stout type 1 foundation.this will be 215INCHES of hold on tight pleasure. go ahead say it cant be done thats ok. thats what some people said about my other misconfigured beast. UD.

Aye caramba!  There's a lot of fat that is going to need to be trimmed off of that brick.

Jeff is like the Buzz Lightyear of Type 1 cubic inches- TO INFINITY, AND BEYOND!!!

I know the answer, but I'm not tellin'!

Man what a torque monster that will be ... imagine if you then turbo-charged it!!!

600 lb ft? :o

Damn ... what kinda cylinders er them??? 8)
Them er real perty ...

YEOW! you have your work cut out for you.
How about a 350" flat 4???????
It just may happen  ;)

the guys down under right.

I had more seating surface and more deck height on my engine. I added a sleeve on the bottom on the cylinders to get a good footprint against the case.

thanks for sharing roman. what no angle flows to display with that case . oh thats right your running those foreign models  :P  ;)  UD..

does every aluminum case have to be welded at no 2 cylinder spigot for a 4" bore?
in my waterboxercase i was able to do it without welding
i bought two CB pentroofcases to do a custom headstudpattern and not have to weld ( i have to space the porsche nickies 2mm apart)
sorry for the bad (cellphone) pic. this is the 3/4 side but you get the idea of how much material was left on the 1/2 side

I don't think you absolutly HAVE to, but from this photo I'd say it's a good idea just to be sure there is a good sealing surface.

The CB case has MUCH more "deck meat".

Deutz cylinders, right UD?  ;D

righto airspeed. thanks to the nice gents across the pond . UD.

wait, 250cu in is 4.1 liters.

 :o

well guys and gals for now we are continuing like always to port the angleflow heads by hand. i never did stop. we just had a vision of just maybe my life could be a bit easyer but no such luck. posibley in 2009 if me and my partner tim aka 58vw can swing a new cnc machine we will do so. as to not to step on anybodys toes in the industry. to many politics floating in the air NO THANK YOU. so until then theres nothing like smelling burnt chinies dye grinders in the early AM UM UM good.gota do whats ya gota do .UD.   

Are there no cnc shops willing to work with you? You have done all the hard work!

tw

Well, I'd like to see the use of CNC just to save Jeff some time and get more of these motors out there ... but to tell the truth I'd rather be able to say, "Yep, Jeff Denham did them by hand. They're art."

ABSOLUTELY!

The case is made by Jimmy, right? Looks promising!

not jimmys case . gusse again.

All off them.

must get alot of black stuff in ya nose. Big boogers in the morning.

we have met with a few and talked to many many others. The few we have met with already have a previous commitment to other shops and/ or are doing there own thing with the heads. Since this is a free enterprise country more power to them, just myself and Jeff would rather not be involved as not to step on any toes. So we will see what works out in the future....in the mean time my good friend will continue to do what he has always done...a killer set of HAND PORTED HEADS. We are commited to see this head and the 4" bore thru and make it available to the masses. we have plenty of heads in stock and cases ready to be set up for your 4" pleasure.

The 4inbore street car is close to being back on the streets and the track soon.

Tim

Looks like the one Fred was working on...dropped cam right?

tw

OK...I just think Jeff is one of the best in the business!
It would be cool to have a cnc,  machine  a set of HIS killler heads.
It's hard work porting heads!

Ya that is the point, lot of work and time and only one person doing it, so the machine would be very beneifical for the bulk of the work and than get fine tuned by jeff from there.

maybe.not gonna say.

Dang, that's a project.
Measure 25 times and cut/drill once!
What's it look like on the inside, UD?

Hey Jeff,
Could you please move that cylinder that is in the way.  ;D
I would like to see the name that was suppose to be cast near the sump  ;)

I always thought that the was going to be "THE CASE" to have  8)

tw

hey tony. i to would like to see the case come into action deffently a bitchen block. im willing to invest in the project with the good guy that started it. will just call him mr.magazine mateiral mopar. when i get time wich is not to often i will machine as much as i can with my milling ability and will see. UD.

Hey UD! Got any updates for us on the "Street" port??? Flow numbers???
Are mine done??? ;D ;D :o

hello tom. i will get back on it as soon as i can(THE TEST HEAD) ive got a couple of tractors engins ive got to finsh assemble first then i will be back. you have a good one tom.           THE UGLY F/N DUCKLING.. ;)

I got the first set of the previous generation finished with the Crower rocker setup.
I am working on the new generation now.

looking SEXY there marty rockers fit nice in the valve cover area did you get much or any warpage when you welded the block? its bolted on to right? 1.7 ratio?.   thanks for sharing. looken good .  ;)  UD.

No they were allredy quite "hard" and were welded a bit at a time. They were then re-heat treated and I had the chambers touched up with the flycutter to make sure every thing was flat and square.

They are a 1.4 rocker. My total lift is only .620 and a bunch of duration.

The heads and cam are for turbo use.

looking good marty

the war zone.

just a little 5356 always makes boo boo better. UD.

booboo all better now. the trusty old 52x38s are ready to thunder once again. UD.

Wau! The whole thread is just  :o. I have done a little porting myself- for friends (watercooled mostly) and i can only imagine what takes to make thing i have seen in those pics. Amusing work!
Just a question about the filler alloy used. I have heard both, to use 5356 and 4043 for the combustion chambers. Some say 5356 is not suitable for high temperature- prone to cracking, the other 4043 is just to soft. What is your take on this? What about the filler alloy for building up the outside of the head, for port enlarging? Thanks.
Keep up the good work!  ... and the pics. ;D   

You know, Jeff, Dean would have been proud of you. ;)

Once again, the Amazing Denham makes the near impossible appear ordinary.
Excellent work, Jeff.

WTF!
Did your kid get ahold of the die grinder?

hello eugene. yes i use both 4043/5356. 5356 defenetly machines so much nicer thats why i use it in the chamber area plug holes and barrel serface area you do have to heat the head up a littel more than you would withwhat you would with 4043 so you wont get serface cracking. i have used 4043 in the chamber also but have to use alot of cooling/ cutting fluid when cuting the softer material. there are some heads that are harder than others so i pick and choose my #s. and yes the norm is 4043 out side the head like manifolds and top of intake ports and fins.  thanks there keith i miss that old timer for sure. hey there tom.  UD.

just grinding out all of the shrapinal that the manley valve and the chines cly left behind. UD.

Thanks. Thats valuable info for me. Best regards

 

Any updates UD ?

Hopefully he is busy working on my heads now. :)

(Though they are not angle flows.)

--louis

I now have valve covers to fit any spring/rocker combination.
The cast ones wont clear much.

very sexy. love the oring.  nice job marty.   UD.

very nice ;D

8) 8)

When Jeff's done with the big block stuff, I want to see him build a 1300cc screamer too. Jeff?  :)

see ya soon buddy

1300cc per side maybe=2600cc

No 1300cc per cylinder ;) :)  Now that would be a big block T1 ;D

cheers richie,uk

 ;) :)

hey you know who were are them there pistons. UD.

Here you go again Jeff. :D

(http://i18.photobucket.com/albums/b115/gold65turbo/jeff1.jpg)

are those a certain 86x101 engine......or 88x101.....or 90x101 or........i give up ???

pure sex wee :)

I'll take 'em!
Texas needs a 4inBore!

to  bad tom.....those were for a 86x101 engine coming to the track soon.
but your right...u need some in texas for sure...big state=big piston

I'm ready to get to the next step!
Just need a few more parts ...  ::)

 :o 8)  Nice seeing you yesterday, Jeff!

cool pick sarge! ;D tom....hurry up...bug in is coming soon....or maybe make vegas ur goal ;D

Thank you! ;)

Tim,
Maybe we'll all meet in Vegas for the 4 inch shootout!
Every time I think I have the right parts, I need some more! Parts, parts, parts ...
Jeff will know what I need, he'll help me out.
He's the Man ... when it comes to BIG bore VW.

sounds good to me...get them parts together and build away!! wow its so easy to say that yet another to do it ??? :( ;D

exactly!

thanks there pimp daddy for the cosmic shot. UD. ;)

 8) 8) 8) ;)

heres one of them there heavy REAL STREET cars with the AF heads i guess he was happy what the car ran he had a  ;D on his face. mid 7s for the first time out not to shabby CONGRATS STEVE.     UD. 

Shhhhh, secrets....  Haha!  Seriously though, I haven't had that much fun at the track in a long time.  The motor never skipped a beat, and kept getting quicker every pass- not bad for getting the crank back the Wednesday before Drag Day (thanks again!).  Next up is a few Thursday nights to start jetting for mph and SEAT TIME SEAT TIME SEAT TIME  ;D

;) ;)

website for 4inbore is now up and more to come on pricing and other related items.

www.4inbore.com

thanks for all the interest

Looking good  :)

Agreed.  Nice work guys!   ;)

Jeff & Tim,

Website looks great!
I can't wait ...

Tom

Those are some nice looking parts you have there, nice to see the site come together.  Now 'yer really cooking with gas- PUMP GAS that is!

Angle flow, 2" modified Berg exhaust, no cutting - plenty of room.

looks good ;D

how about something on the smaller side. 50x38 94 jugs high cr 125 incher. slowley in the works for a certain someone.   UD.

Hi Jeff,
          what rocker set up will you use for the roller cam stuff? Any pics? thanks. David

seats installed in the small CI set ductil iron.  crower rockers on that project will have some pictures hopefully soon.UD.

are those for me!? ;D

Jeff can we get a shot like this? I’m curious to see how you fit those size valves in that cylinder. Thanks. Casey
(http://i75.photobucket.com/albums/i313/vishfab/Photo_100707_0131.jpg)

Hi all,

The work done on the head is very impressive,
Have got a question about the work done under the guide valve (see the attached pic 1), I would like to know why you grinding so deep under the guide?
As you see on my last head (see pic 2 -3) I shaped an edge under the guide for an aerodynamic purpose.

What is the best shape?
Have you done flow test to compare with edge one?

Many thanks for your tips

Very impressive. Thanks.

hello pig 1200. any who ive never ported it the way you did. ive seen it this way before. no i have never done a back to back flow test and compared the two. my idea is to stratian the port out as far as i can behind the valve.the roof on these heads is more difficult. i have had good sucsess doing it this way.there is plenty of meat there. i would feel that airspeed would be better your way wich is a good thing but max flow may suffer some. .just my thought. UD. BTW good job.

I was rereading thru this thread and thought it was SO COOL and had such great information and pics, it deserved a Bump (with a capital B!).

Going thru the pics and seeing the metamorphosis is truly inspiring.

Many thanks to UD!

TexasTom

thanks for the kind words like always tom if it wasent for people like your self i would have got out of this racket along time ago.on another note me and my freind tim went to vegas for one hole DAY wow big vacation  ::) it was fun wile it lasted (THANKS TIM)  here is a picture of the red barrons engine i hope he dosent mind this. he has every body coverd like always. its just great to see him running the AF HEADS. and congrats to all thats involed with his rocket i hope the best for ya. i wanna see a 7  ;D. you guys can do it. good luck to ya . UD  .

hey jeff .
how you doing .

Is the Baron running a 4" engine now? Looks like they finally ditched those old Race-Trim covers! :D

yes he is...and you can here it in the tone....all the way up in the stands....thunder ;D

My friend Ethan Doubleday made the injector holders on the Baron.  8)

http://ultimateaircooled.com/simplemachinesforum/index.php?topic=2758.0

very nice

its sat so i thought i would do some rocken around. UD .

Just AWESOME dude  :)

What ratio you runnin Jeff, 1.7s? What are you lookin for for max lift, .750" ... crazy! :o
It very much surprised me to hear the stainless steel rockers by Crower have a lower moment of inertia than aluminum ... I have no way of proving that statement, but it would be interesting to know the truth.
Will the block under the rocker bolt in or weld in? Looks like the Angleflos have plenty of meat for darn near any rockers.

Looks like fun what you were playing with ... I spent my Saturday getting my 2276 longblock back together. Compression should be right this time.
Yeah Tim, I know ... going backwards! :D

Looking forward to shoehorning the 4"/Angleflo monster in it's place!!!

hey tom. there 1.62 should have 760. small lift compared to some. i wanted to thure bolt the hole thing but with the gussets on the bottem i may have to do some tigen. UD . 

I think the weld-in option is the best. It should make the whole rocker box area much stronger and up to the abuse of any valve spring.

(http://www.m-specmotorsports.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=1753&g2_serialNumber=2)

how much warpige did you get if any. i would think it would try to pull the end valve cover rails in even when welded slowly. UD .

Preheat the head (a lot) no warpage

..UD .

Did them bare, re-heat treated them, and the went over everything to make sure and get it all flat again.
They did not move too much to be honest.

what springs you runin there marty?

I think these are at least 25 years old

Wonder if I can find a invoice from Fumio -- nah probably long gone

old school AF's there ;D

hey jeff...what gives the the goober peanut butter and jelly.....thought it was a cheese samich

PSI

thanks for sharin marty ;D

x2 marty.

Also, I am only running 1.4 rockers.
That is all I ever run with the cams I use.

LOVING THIS THREAD!

My comp elims blew so had to welded them up then machined them back, but nothing like the AMAZING work thats going on in this thread!

thinking about doing the rocker shaft mount now lol

I bolted my Crowers in
(http://i32.photobucket.com/albums/d18/autocraft/01022008186.jpg)

the mounts didnt fail, but the rockers did!
(http://i32.photobucket.com/albums/d18/autocraft/brokenRocker.jpg)

Changing onto a different rocker altogether now. with a little luck they should arrive on Monday.


Martin

???????

Something was not right there Martin.
I have a few cars runnign those for years now with no issues at all.

X2 what marty says theres somthing not right did you investigate thurily?. proper shimming maybe deffenetly was eating it self oil delivery maybe good luck to ya hope you figure it out . those look like the paridice billit heads yes? thats some pricey stuff ya got there my freind ;). UD .

ive not torn the motor down yet to measure the spring pressure, but once you start to look at the rocker all the load is put on one bearing, i did a search on the bearing and got its load ratings, it would seam were way over there limits.

if you look at the rockers from above and draw a line from the roller tip to the push rod cup, you can see where all the load is applied.

As for oil, thats not a problem theres loads of oil directed at them.

I know ive got to make sure that the springs are in spec. Im sure they are with in 10lb of there original spec. Ive been running them 0.090" off bind so they dont jump around at 9,000 rpm.

I'm on my 5th cam design now (learning more with each spec) and the new one is going to need even stronger springs. so i want to nip this problem in the butt.

current springs are 698lb on the nose. going to have to step up to 800lb springs for the new cam.


Yes UD there paradise billets. fortunately the rocker boxes have plenty of material in them!


I'll post the next incarnation on the 'in the works' page Sir Don Pauters has made me some special rockers to try out.


regards


Martin (every day is a school day) Taylor

Martin, I get the rockers from Geers and maybe he has different bearings installed that the standard issue?

The only other person I have ever heard of with issues with these rockers had their valve springs installed wrong (something like .200 from coil bind).

Example, this motor has 750# over the nose and has been running for three years straight and the valve train has been rock solid!

(http://www.m-specmotorsports.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=928&g2_serialNumber=2)
(http://www.m-specmotorsports.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=910&g2_serialNumber=2)

The exhaust seats need a touch up each season but thats it.

how many miles does it do on the road? and how aggressive is the cam?


Martin

LOL - it is NOT a road going car so that is a very good point!
The cam is pretty agressive.
(http://www.m-specmotorsports.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=919&g2_serialNumber=2)

If you are getting some of Pauters latest rockers, you will be quite happy with them. I have them on a 900# spring motor right now ;)

Yeah there the 'development' rockers from Don, I dont trust the Crowers anymore, not for what im trying to archive.


Martin

Nice cam there Marty -- I remember having to clearance the heads on some of my Drag bikes to get the cam turning inside of them too

From the look of the cam, that is plenty.

I just freshened up another of my Crower equipped motors - no issues at all.
750# at full lift.

(http://www.m-specmotorsports.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=1234&g2_serialNumber=2)

I am thinking there must be mutiple versions of the rockers.

nice..thanks for sharing ;D

Wonder why the Crower Stainless rockers aren't used more? In some configurations, they have a lower moment of inertia than the aluminum versions ...

its been awhile.  ;) UD 

Jeff!
How did you spot-face the stud holes for the washers both under the rocker box and behind the intake ports?
My 94mm angleflos could use this treatment, esp. behind the intakes.
Looking GOOD!

I was thinking the same thing, great work!

Don't know what Mr.Denham uses,but a possibility would be a "back spotfacer" like this :

I've made a couple of simple versions with some steel bars and pieces of removeable toolbits ;)

the handy dandy spot facer.  ;) UD .

Ah HAH!
That's what I figured ... looked them up on the MSC website.
I think I need one of those ...

Thanks Jeff!
Hope you're doin' very well.

p.s. I have room for that assembly down here ...  ;)

looks good... ;D

That is a pretty cool tool there Jeff.
In Australia our range of tooling and costs are bogus.
I should get my tooling from over there.

I had a similar dilema with my heads, where the 10mm 'extra' stud interfered with the plug spanner,
and also, the nut always trying to lean over into the cavity for the centre two top ones.

To I made this tool to spot face down to the next fin, which was the same height as the centre two middle ones.

Very resourceful!

very creative there dave im sure it works great. i had somthing similar until it broke a couple of weeks ago when i was right in the middel of the job. so i had to make a trip over to wally,s tools in orange i bought two differnt size,s they were cheap $50.00 for both. UD .   

The heads are in Texas now, but not at Tom's...     :o

WHAT THE ... ?

Ugh.

Now it's a race to get 'em running! :D

I think you got that race won.  I still have to build the car.

tom...there is no time...remember..work work work.......we all want to play play play though....

hope to see those heads and cars running soon

I have to build the car too, but did get some work done yesterday ...

Plenty of room for those big bores and giant AngleFlos! Bring em on.

So who is winning the "get the car running" race Ric or Tom??????

It's gotta be Ric!

The rate of progress I'm experiencing could surely be eclipsed by an attempt to recreate Stonehenge and the great pyramids with original specifications and building materials! :P

Anyone know where I can find a reasonably priced human body, around 5'11" and 170ish pound stature? Surely a complete transplant would be more effective than replacing/rebuilding all the problem areas ... LOL!
