RacerX#99 Any head gasket will Blow if it is not the right application. If I was to run 15 pds of boost, the heads and the block would be Oringed and either a solid copper gasket for short racing or a SS gasket. All hardware would be ARP also. Alot of new motors and blocks coming out have more than 10 head bolts now. I will let you know after I get the blower back on my car. With 9.2 compression and intercooled about 12-15 will be the limit. The shelby block only has 10 bolts, sorry Studs. We will see if the gaskets blow
