Default 5.7 heads on 5.3?
will 5.7 heads work on a 5.3 & if so how much would they have to be milled to keep the same compression?

if you dont mill them (in order to drop compression) will the still work, and what head gasket would work best

They will still work. Any gasket will work, the smaller the more comprssion and less quench you will have.
