Literally everything we follow in the world is because somebody wrote something on a piece of paper, like the constitution and whatnot.

OP, why not just go with rams head manifolds and high flow cats? If comfort is more important than HP, seems like the easier route. I understand where you are coming from. My ‘88 burb with TBI had the cat deleted before I got it and it is noticeable just by the smell. Not a rich smell, just an obvious smell there isn’t a cat installed.
