What is your general goal here?

I mean, it sounds like you have a CAM that is dictating the engine build.

Think about the fuel you are using. If you are out for premium fuel, then 10 to 1 or better. Get a piston that forces that much compression with your heads. Milling heads for compression is a bit rough in todays market.

Start out with a list of wants.

Stop entering all these problems into the mix. Get a block. Pick a piston that will give you your desired compression. balance and blue print the assembly.

Personally I would work with the heads as they are and unmolested. You can build that top fueler after you have this one under your belt.
