DON’T BE FOOLED!

“Within reason” is a big qualifier to your statement which is basically true, until you try making big power, (+1000hp or so). Boost is just a multiplier and the more power you make NA the easier it is to make power on boost. So at some point the head is a restriction and needs to be upgraded.

That Dart( Fink’s car) I am sure was making WAY north of 1500 horse to the tire with the B1BA heads on it.
1000 horse isn’t much these days. Literally junkyard stock LS stuff with a Chinese turbo is making power like that
That said, I agree with you. Just saying 99.xx% of people with a turbo deal can go way faster than they could dream of, even with non killer heads.
