Class of the Head

If the head ports CC correct and the chamber CC correct and they look "as cast" there is no policing they can do. Reshaping, welding, and coverup work of bowls and runners, shaving intake side of head to bring CC's down when runners are enlarged, cutting bottom of heads to bring bowl back to specs after you unshrouded the valves and covered it up.....Am I getting close? lol oh and of course the intake has no measurements in the book so "as cast" is good enough even if it's bigger than a sheetmetal intake lol. When one car can run to 6800 at the shift and the other falls over at 6200, same casting numbers, same cam and valvetrain, same trans/converter, same rear gear etc etc.....someone if moving more air thru there air pump(engine) Anyone that says this is not being done is lying to their self. Round trackers been doing it for decades. The question is ??? if you can't beat them, join them??
