I wanna buy a cometic head gasket for my soch z6 motor.. On the nippon power web page it ask you to select the bore size. Which size bore should i get(75mm to 79mm). Also what thickness should i get(.027 to .058inch)
My car has the greddy kit on it. I'm planning on boosting 9-10psi.

 

So any of you soch guys wanna tell me witch bore size and thinkness should i get...
I don't even know what bore size is anyways..
thanks.

 

just hang in there

 

so any of you z6 soch guys can tell me what the bore and thickness i should get

 

I remember stock bore is 76mm and stock height should be around .42

 

ok...i've found out the stock bore(75mm).. now can anybody help me wiht the thickness is should get....thanks..

 

Get the thickest one in the "High Output" design...its worth the money and you can't really go overkill on a headgasket.

 

.31 thickness is stock.
