new heads witch one ??

[thehanz DVK]

i am in the proces of collecting parts for a 2332 cc engine for my 67 bug

already have the case , 82 crank, h-beam rods and a lot of smal parts, i want to build a race engine that can be used on the street to drive to the meetings

my thoughts are

cb cnc heads  with 44- 37.5 valves   samba price at serranos around 800 dollar a set
or bugpack superflow heads  44-37 valves                          around 800 dollar a set
or even superflow                48-38 valves                          around 850 dollar a set

this in combination with a set of new 48 or 51,5 IDA carbs
 any pro or cons to these heads ??

also the choice of pistons and cilinders a set of 94mm from mahle or is there a better choice, when you keep in mind
that there might be a possibility that i want to ad nitro to the engine

hope get some ideas to give me a direction

superflos and highway driving usually don't belong to the same sentence

Maybe not in the right lane, but in the left!!

alex why is that ?? are they to agressive or simply totally wrong for this use ?? and wear to fast

[Lee.C]

I just picked up a set of Scat D port heads 40x37.5 for my "BIG" engine - Not sure if I'm gonna do a 2110 or 2332  - they do have slightly smaller valves but I do know that these heads can run 12's on a 2110 so they should be fine for a street car - Any thoughts people

Maybe because they have a rumour for running hot?

I`m using CB 044 Wedgeport heads that is ported, with manifolds that are welded and ported and with the LS1 spring/valve package. They work great for both street and race driving. Roman did a 11.29 rund with the Wedgies so they can be fast as well.

so it looks like the cb head is the wise choice for street and strip use, when the superflow's run hot it's no good for a few hours drive...

The potential is certainly there with those heads. Today you can get them complete with the LS1 package.

when you keep in mind
that there might be a possibility that i want to ad nitro to the engine

Nitro? As in nitromethane fuel? Or nitrous oxide? Nitro and Nitrous or very different things. Nitromethane(ch3no2) is a basically liquid TNT and will blow the heads off but you might get 500+hp for a second or 2, depending on ratio of fuel to nitro. Nitrous oxide is an oxidizer that is injected and introduces a compact charge of oxygen rich fuel. You can do alot of damage with n2o also if not conservative.

i was thinking of nitrous oxide but needs lot of info before using...
at the minute i think i will go for the 044 heads witk 44x38 valve's and a decent headjob...

i think they are a good choice for that price..i also think about to order a pair for my 1951ccm...i had seen them ported out of the box and must say, good working..And not so big combustion chamber volume like other heads (044 wedge ported, Steve Tim heads etc or so..), so you can drive these heads on smaler engine < 2000ccm with a good compression (10:1 or bigger) and not 8,5 or 9:1...If you have those big chamber volumes you have to cut and bore lower in the heads and have problems with high lift cams and ratio rockers, so you have to make valve pockets...
So it is a good head for the price...

Thanks for the info Tom - I have been thinking about doin a smaller engine ie: 1776 or 1915 or a 1904 or maybe even a 1968 as it would be a bit more old skool 

Has anyone got any GOOD sub 2 liter combo's

[nicolas]

at the minute i think i will go for the 044 heads witk 44x38 valve's and a decent headjob...

i say alway go for a good quality headjob  can't go wrong with that

i would run cb heads with 44x38 valves and still have a 'streetable' head.

as for a smaller engine combo; 1776 cc with a w120 engle cam and a counterweight crank. 40 dells or webers , 44idfs maybe or dcnfs for an oldschool look. look at kanase's car of dkp, you'll get a good idea  love that car

How abt this heads - anyone got any experience with them?

[alex d]

a good question would be "who ported them?"

there are lots of good head porters around, and they have the numbers to prove it!

[Udo]

I think it depends on where you are living if a head is good enough for the street . If you live in a country where you have a speed limit you can run 044 CB heads with no problems . In Germany we have no limits and people want to go fast for a longer time. This is why I only recommend stock 040 heads and 90,5 bore for street use with relocated spark plug holes you never get problems with cracks and the best cooling for the chamber and exaust ports. The 044 heads can be used with 94 bore and only cruising on the street , and never use a superflow head on the street . Also we had broken exaust valves in 044 CB heads , so almost take manley valves for these heads .
This is what I found out on street and ciircuit race engines !!

Udo

[thehanz DVK]

what i have decided at the moment is to go with the 044 and the headjob will be done by steve's vw shop in belgium, and the valves he uses are the manley's as far as i knowe and yes there is a speed limit in the netherlands as you knowe...
for daily transport i have a type 3 notch and this engine will be for the 67 bug for fun, a bit cruising and traffic light fun, and dragstrip practice...

and thanks for your knowledge udo B...     i think
when i read what you write i think for my use it's okay

[Udo]

OK , for this info i get a beer at the bugin 

[alex d]

Udo, what's your opinion then on the new thick wall 92mm cylinders? Have you tried them? They look like they would be  really bullet proof (on paper at least)

[Udo]

I never have seen them .

 To keep all head thoughts/experiences in one topic, i've put my question here...

 What are the experiences with Steve Tim's stage 1 or 2?
 Are they worth their $$ and how do they compare to CB 044's?
 

[The Ideaman]

I think Zach's friend, "Fruitcake", runs a set of  Tims heads on his 1914 equipped 67.  With 3 gears it has run 13.80's in the Arizona heat.

This is the car, and I believe he drives it daily.  Zach can tell you the rest of the combination.

[Jordy/DVK]

 Zach already told me...

 Do those 043 castings cool much better than the 044s?

[The Ideaman]

According to Udo and Turbo Bob, yes, they do.

[Zach Gomulka]

Yep, thats the car. 1915, 9:1, K8, Steve Tims 42x37.5 043 heads, 1 5/8" merge 2 1/2" muffler and my IDAs with 37 vents. 4.12, 3.80, 2.06, 1.32, .89. 043s do have more surface area for cooling if heat is a major concern. I believe Tims prefers the 043's because the aluminium is better.

[Diederick/DVK]

4.12, 3.80, 2.06, 1.32, .89.

Is that a long ratio box? I'm always troubled when i read those ratios 
For some reason i tend to think ending with .89 is long and if it's above 1 short.
But then there is still r&p 

Anyway, looks like a strong combo

The only thing different from those gears and a stock 67 box is the early VW 3rd 1.32 gear. I believe 3rd was originally a 1.26. I like how that gear evens up the gear splits from 2-3 and 3-4. BTW, he uses 215/65 radials (26" tall).
