David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

If you go by these formulas for a second (say there in the ballpark) and calculate what's too big for a 318 to make peak power at 5,000 rpms the trick flows come out to be slightly lower than the lowest acceptable velocity. But if you put a set of trick flow on a 318 even with an rv cam it's gonna make peak hp in a higher rpm than 5,000 rpms, probably moving them up to the lowest acceptable velocity.

Now obviously no one is recommending trick flows on a mild 318 but say there even technically fine I don't think people overly have to worry about lesser heads much. Now of course you can debate the validity of the formulas but unless your trying to run trick flows or bigger on a mild 318 I don't think you overly have to worry how accurate the formulas are.
