Who makes a good one and do you have part numbers and/or links? Oh, ARP studs as well if you have that information too.

I know Cometic has 3 different sizes, but none for the 86mm bore. Thanks ahead of time.

contact them, it's the brand i'm getting and i believe twincharged is running on his car

 

What series are you getting? The pro or copper, and they make one specifically for our car? I'm going to PM you as I have some more questions on your car.

 

This is the copper head gasket from the build book if you plan on going over 22lbs of boost.

Thanks for the info. Damn that's expensive for a head gasket though!

 

here's the problem with that one:

 

^^^That's probably why I won't get it. We'll have to wait and see what's up.

 

****... I'm running 21.6 psi right now... I see a new headgasket in my future... damn... oh well, pay to play

 

how the hell are u doing that on a 2.6? I'm running a 2.5 and not seeing it that high...tho im glad im not...its a measurement or restriction on these motors.

 

that was with the 2.5... I have a stock exhaust still so I think thats what is doin it.. It only hits that at like 7200-7400 rpm though... normally its 19.5 to 20.5..

 

whew had me concerned for a sec..i got stock exhaust but no cat...makes a big difference

 

I know... I'm waiting for my header to come in then I'm goin to a three inch custom setup... and I"m doin a blower porting this week or next, plus I need to change my intake piping... should have that by the weekend.
