wow died you are fast with math and time haha

yup.. The mexico of Asia

LOL!

[Diederick/DVK]

mmh, i'm not much for quizzes
but i'd have to go with thailand, partly given the presence of a cal-look scene there

Udo -  the heads have the casting :   113.101.375A 

         any insight about these castings?


died - hehe   wrong answer, try again hahaha

[Diederick/DVK]

tried to find the solution using your expression of mexico of asia, and there's a number of countries who call themselves as such. thailand, korea and philippines. i'm gonna go with the last one, then.

[RFbuilt]

you're right though

Thailand has sum cal look heads brewing up in the past few years

If you cut the guide boss for double springs they do not have enough press fit for the guides. without aluminium nose inside the port the guides do not have much head material to fit. This is what i recommend,may be others think different. and with your small carburators the engine does not make much rpm's that you need double springs.

interesting input there mr Udo.. thank you...

that is fine i guess...  since im also pressed to rebuild the 1300sp off my 1979 beetle,  i myt use the 113 head on that, being a stock mild rebuild  , with just new single HD's 

for the 88x74  , looks like i need to find another set of DP heads then...

all good hehehehe (time to go hunting again)   

[RFbuilt]

due to lack of experience...  once again i need opinions on the ff:

 

since the 113 heads as noted by UDO would be good for single springs and milder use..

im opting to use that pair of heads on the 88x69 rebuild , mostly stock with the exception of the kads and extractor type exhaust..

having a hard time finding 040's or any used but in decent condition dp heads local to me..

i figure , maybe i should bite the bullet and buy a "new" casting in the u.s.  but being pressed for cash

the GO1 / autolinea heads sounds interesting ,  i think theyre similar to the 043 heads?
except with 35.5x32 valvesizes

is this ok for street use? 

i found an economic aproach that would let me buy a pair of these (complete heads)
and i can put the stocker valves,springs etc into the 113 head after freshening up

and the "bare" head would be refitted with the BP valvetrain and possibly ss valves

any comments on the GO1 heads for street use?


sorry guys for too many questions LOL

[RFbuilt]

any comments on the previous question?   

imexcited and ready to order, but got a little worried with Udo's inputs so.. i wana be sure hehehe


cheers y'all!!

Stay away from the GO1´s. They are not woth it.

I think you misunderstood Udo a bit. The stock 040 can handle dual springs, no problem. You just need to be a little carefull not to take too much trust out in the intake port for the guide..

[Udo]

Thanks Torben..

Udo

[RFbuilt]

thanks torben.. in part of me and Udo..

i do get what Udo meant, however , i have a 113 casting head...

"not to take too much trust out in the intake port for the guide.."

what did you mean by that?

if you mean, "watch out" when porting certain areas in the intake ports?  (if thats so.. then im ok i think.. i can be careful)

or did you mean the outer dia. of the guide boss on the valvetrain/springs side?  does it get weak when the head is cut for duals ?

in anycase,  if the 040 factory heads are safer for duals.. vs a 113 casting head,  i will def try to find some 040s local to me..

the 113 head will just need to be used on the project 1679cc  as thats gona be a very mild rebuild with just new single springs


hope you can clarify my misunderstanding Torben,

thanks for the valuable inputs!


and i miss Jim.. LOL where's he hihihihihi
