I'd keep this simple. Get the heads ported well. Run the old tried and true TRW/Speed Pro forged 12:1 domed pistons and use the .590 MP solid flat tappet cam. Simple and effective.
I agree with the exception of not using the mp cam as those cost twice as much as better designed cams from Hughes (I know, not your favorite lol) or Howard's, and damn those pistons are heavy as hell. But still work!
