how do you pick header gaskets for SBC
I have a motor i built with doug thorley tri-y headers (vortec edelbrock e-tec aluminum heads) and the gaskets that the thorley's came with are already blown? Not even broken in yet. there is no noted torque spec. on the header paperwork. Does anybody have a gasket they can recommend? This build has been going on for far too long!! I would love to be done with it. It is in a 96 chevy express hi top conversion van.
