Just got a set of AFR 165's

[90GT398]

when has rpm ever dictated flow? rpm dictates velocity into and out of the head, either that or some of the best engine builder's in the USA have been lying to me. LOL

Trying to compare a dedicated strip car to a street car is like comparing an apple to an orange, do both cars have the same suspension setup, gears, weight(that's the big one).

The flow on Pure Street/Warrior heads is not what simple think, they have to make so much more power with lower lift numbers than they would up stairs with a street head.

This is my last post on this subject because head discussions never come to an agreement anyway, good discussion though I will admit that.
