Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best

I agree velocity is important but I think over worrying about leads to strangling your engine, say you have a zero decked 367 with a xe285hl cam, for most their choices for heads is what is available, at the very least stock 1.88 heads and max for most trick flow. It comes down to $$$ and how much power for most they have little control over it.

Velocity like everything else about balance and compromises, too much of anything can be bad.

Doesnt seem to be many SBM heads that are "too slow" to begin with either.

I think people worry themselves with port velocity to rationalize not going to greater lengths with their porting. Over-porting seems mostly to be a worry when people focus on the wrong areas and wind up with wide and narrow spots along the port or just blow out areas that are easy to reach.
Or they just ruin really important spots thinking they're improving things...

Also because people are cheap and think offset rockers are too complicated.
