I'll probably pi$$ off somebody here, but for this sort of application I think some of you are getting way too hung up thinking Brian's heads having FPS readings being too high and exceeding their "theoretical" max flow limits. Is it "better" if your port design results in measurements that fit within these ideals? Probably. Is it going to kill the head's performance if they don't? Nope.

Example: My old Stage VIs were only 213-215cc ported, had a standard 2.20" x 1.20" entry w/ a pinch significantly less than that due to the nature of the port. They flowed 305+ at .600" and made over 600 HP on a pump-gas 440 (10.8 CR) w/ a .600" solid flat-tappet cam. That was enough to push my 3755# (w/ driver) street car to 10.5s at 126 w/ a full exhaust on DOT tires. FPS? Almost 400 over the short turn. Yeah, it would have been nice if the air speed was more in line w/ the ideals and "should" have performed better if they were. But that's what they were AND how they performed, regardless.

This ain't Pro Stock stuff here...
