Port velocity average target fps?

@273 As a late thought entry, if you’re just building a regular street hot rod, IMO….. the trick flow head is about the best bang for the buck. It has a small port with high velocity and flow numbers. On paper, it’s a 600hp capable head.

I have it on my wife’s 11-1 - 360 with a dual plane and a small hyd roller and it’s really excellent for what it is. There are a lot of short comings coupled to the head the militants max out put. A dual plane intake, small cam duration and not taking advantage in valve lift vs the head flow. But it’s also designed to be a total driver anytime anywhere and it does great.
