arp head stud kit / cometic vs durapro

also do cometic make a gasket for the sohc , if so what is the part number .
i have seen a gemini use a durapro graphite gasket and pump 35psi into it no probs , using a head stud kit .

There is no such thing as an ARP 4g63 sohc head stud kit. There may be
other stud kits that would work but good luck finding out which one. 4g63
dohc studs are to short to use. I have heard of Ford Cosworth/Sierra
head studs being used as they are the right length but you must helicoil
the block first to change to the new thread. ARP have never bothered to
help me any when I have emailed them.
Cometic dont make a gasket for the sohc but you may use one for the
dohc as they are basically the same. You have to get the right size though.
Sorry I dont know anything about durapro gaskets.

what about g54b head studs? I know dohc headbolts are the same threadpuitch and what not, but g54b are a bit longer. Might be worth looking into. I could probably measure a arp g54b stud out and let you guys know how long it is.

twin cam one are actually too long when my workshop tried using them, so he went for the g54b ones instead. you can use vr4 one so long as you use a 10mm spacer made from stainless and i think they need to be 32mm in dia, use these on top of the studs after the head goes on.
here's my engine before assembly
arp studs with an oring'd head and block and a copper head gasket were used. This should hold 30 psi of boost no probs.

boost = the replacement for displacement
