Are the heads as cast or some modifications? What are the CC's of the heads and style of piston? How big a dome?

No dome.  74cc head as measured, 20cc dish piston.  Pistons were .015” out, used a .056” Cometic head gasket.

No port work.

No head porting then... So a nail head valve or a tulip valve on the intake? 45 degree deal!?

I would encourage everyone to scroll through the dyno results section.   I have both 428CJ and 427MR engines up there to compare off of.   There have been some very liberal guesses lol
