I blew my cometic because I was using stock head bolts.Now the gasket is on backorder!I now have ARP studs and thought of using a stock gasket until the cometic came in.It is on a zc and the honda gasket is not a multi layer metal gasket like a B-series.Do you think it will hold??????????

 

No i wouldn't rely on stock if the cometic couldn't hold up too it.

Find another place to buy a cometic one.

 

even with arp studs?

 

yes, stock headgasket

our car has seen 35 psi on a stock headgasket - bored to our engine size by golden eagle

 

Stock owns Cometic...i have seen cometic gaskets blow with 8 or 9 psi...To thick and that makes them weak.

 

Stock all the way.

 

are you saying that you were running a cometic head gasket with STOCK head bolts @ 24 psi?? or is this what you are planning on running(PSI)?

 

yes stock headbolts and 24psi and it blew the cometic in half

 

Cometics arent too thick if you get the stock thickness.
but i have the Stock headgasket stamped out by GE and was told they have run 60psi thru thm

 

Isin't the ZC gasket a carbon gasket?? If it is then there is no way it will hold 24psi, it probably wouldn't hold 8psi.

What I want to know is.....how the **** did stock HONDA head bolts withstand 24 psi!!!!!!!!!!! what size turbo are you running?

 

He is not running a traditional multi-layer OEM headgasket like what is on the Gsr, etc. The ZC headgasket is not like that. I would do some more research to see what head gaskets may fit OEM style.

 

T3to4b and believe it or not it held for thirty dyno runs and 3 passes down the track.I did some research and nothing honda/acura will match up physically or by part#, for the headgasket that is.

 

By the way, the stock gasket held 11psi and lasted for 2 years until I pulled the motor to build it!!!
