440 build 500+ hp build

Thanks for all replies!
Headers will be custom made, owner of this car is a pro when it comes to stainless exhaust so no worries here!
About intake, well he loves old school max wedge dual carb look and frankly I’m curious how it will affect the build. Let’s give it a shot!
About head gasket, I was thinking to use .027” mls but do I really need to worry about it here? This is not all out performance build.
This gasket puts me at .045” piston from head where standard felpro gasket at .056”… I have both gaskets so probably mls to get the most off it but I was keeping these for my own engine ;-)
