Have a old block 302 that has been built. I put procomp heads on it. Cobra intake which I had on my other engine and stock heads. On this new motor the bolts match gaskets and heads well, but seems to have a pretty good gap approx 1/8" or so on the ends which seal against the block. I havent torqued it down because I was not wanting to waste the gaskets. Will this seal as I torque it down? Heads havent been shaved. Block is .030. Thanks. -David
