Why do practically all the hotrodders seem to think that increased power always comes at some warp speed RPM that a stovebolt cylinder head can't possibly accommodate ? Why not build for a reasonable increase in low end torque? Some engineer's wet dream of a cylinder head might be a good exercise in wishful thinking, but let's load up the beds of a couple of trucks to max gross weight and head up a few steep hills. "Horsepower is to brag about- - - -torque wins races" (and hauls a payload!)
