I have a 4g64 87mm bore block from sbr(slow boy racing)aka built industries ,I need a head gasket which cometic h/g do i order ? i was sent a h/g from sbr but they sent me a 4g63 87mm bore instead smh.....

 

PE Head Gaskets are great.

 

i used the one that awd motorsports sells. its a stock headgasket bored out. i have also used power enterprise. the awd one is cheaper and help 40psi. i have heard a couple people having problems with the pe ones. could be install error but just throwing it out there. g/l

 

English Racing uses the Cometics now, message JohnBradley (who's name is Aaron) he'll get you squared away.

 

sounds like the one they sent is right? 87mm bore is what you needed, I got my cometic from extremepsi COM-H1528SP6051S was the ##

 

I popped a PE recently. Now using a AMS OEM modified one.

 

I'm in need of a good hg too for my 2.4lr build, any more input would be great guys... Tnx in advance

 

I am going to be using the OEM MLS one, with 32lbs on a hx40 with ARP head studs...just sayin

 

i am using a pe head gasket so far ive only pushed 25psi so well see on how long it will last. if it does fail i will get an ams modified oem one

 

bored out evo 9 gasket (even on an 8). its proven time and time again.

 

^ bingo thats the way to go. and 87mm bore is correct for a 4g64

 

ok well even the 87mm 4g63 gasket they sent me dosent match up with the water passages on the block ?

 

some of them wont. certain holes are blocked on a evo 8 to a evo 9 gasket.

 

Why arent you guys just using the OEM 4g64 MLS one?

 

Has Cometic changed their 2.4 head gasket? I used a Cometic in my 2.4 build and the head is lifting, been lifting since last year at around 500. Getting ready to go with a new gasket soon.
