Ok,first big block build. I am installing edelbrock performerintake onto aluminum heads. I purchased a sheet metal valley pan and I just can't trust a bead of silicon that long down the sides of pan where it meets heads. Any re-assuring "it won't leak " tips? I foresee an oil leak and a vacuum leak in my future.
This is than than just butts up against bottom of heads, still using normal paper gaskets for intake to head.
