To me this all combo dependent, for the most part most builds use generic parts.
Take Edelbrock Heads and Air-gap and comp xe 275 or 285 cam it's a general decent combo that can go on many different short blocks it's not tailored for each short block and stands to reason some will work better than others but will that go from largest to smallest? And what with slightly different parts? If we maximize port shape cam timing etc.. For each combo what effect would that have? Or does static displacement will always win out or does it even? What if you factor gearing does that change the results?
