Blown Head gasket 302 with a 671
 

I have a blown head gasket on 1976 sbf 302 with a 671. The block bored 30 over. What size head gasket do I need and what is the best? Copper? I am running the boost 6-8 psi it's 18% under driven. I need a model #.

stick with a felpro series head gaskets esp. the black type gaskets / what is your compression numbers at also what is your fuel system like just make sure you didn't run lean and blow the gasket that way as well good luck joe g 8)

Depending on what thickness you want...You can go with a cometic C5511-xxx gasket and be good to go.
