I have my set on a vette LT4 crate engine pumping out 395hp.

The heads on the crate engine are LT1 aluminium vette heads. My question is what do these heads flow HP wise?

Would I be better off replacing the LT1 heads with a set of Fast burn aluminiums? Would they even bolt up to the LT4 intake??

Here is the specs on the engine:

This is a Corvette Motor with LT1 corvette heads 64cc chamber, comp 10.4 to 1, cam specs crow roller cam duration .050 218/226, advertised duration 289/286.

Could I get any better CAM for this combo?

Is 10.4 to 1 Compression ratio too much to be used with a Supercharger? Might have to get the compression lowered..
