Anyone install Edlebrock aluminum heads ?

Not a valley pan. It looks like a regular intake gasket that has a round or similar shaped hole where the heat crossover is. They provide the correct shape piece of stainless steel to fit that hole.

Put the gasket on like normal and put the piece of SS in the hole and bolt the intake on.

Done.

Plus, if you have headers (which means there is no exhaust crossover flapper) very little exhaust will flow thru the intake manifold. And certainly not with enough pressure to blow out a block-off intake gasket. The stainless steel block-off plates that come with some intake gaskets will last forever (with headers, or exhaust crossover flapper blocked open). Or get some .020" stainless steel and make your own block-off plates.
