I realize this is somewhat connected but it is also a derail of @NC Engine Builder thread. I'll try to keep the head posts more directly connected to the dyno test and address the hypothetical elsewhere.
Thanks for saying that. The theory is interesting but IMO once you get into this type of discussion you’re essentially beyond the main purpose of these replacement-type heads anyway. Plus it’s only one aspect of the equation.
Sure, anything can be made to perform better with enough effort but frankly it makes little sense to start from point A and then put in whatever work it takes to get to point B when you can just start at point B instead.
