Ok here is my problem seeing if any one can help

zo6 heads (243 casting) untouched
231/237 tsp cam
stock rocker 1.7

i need a new head gasket was wondering if i can gain any more compression by using a thinner head gasket.While still being with in safe margen for P/V clearance.

if not would you sugest staying with the stock GM gaskets.

 

any ideas anybody?????????????

 

clay it and find out.

 

That is pretty expensive answer. You would have to buy three different types af head gaskets that i know and then clay each one that is close to a $400 test in head gaskets . Just seeing if any one has gone through this for some tech help .

thanks
