Port velocity average target fps?

To Chad in the video fps and csa seemed to be the two most important aspects which means the flow is the one that needs to be adjusted. Not saying that's how it must be done, he just was vague on the one part he seems to consider most important.

I take all this stuff with a grain of salt, most us aren't building max effort engines, some seem to get super focus on one these max effort aspect of performance and lose site of all the rest and want to apply it to everything.

Especially out of place when people want to do a basic 4bbl cam exhaust and tune to their stock running engine.

For me it's more about the puzzle of it, I like adding pieces.

Chad is coming at it as a racer chasing every last tenth, so it makes sense to start with velocity and cross section since it will be defined by the rpm and induction allowed by parts allowed.
Like you're getting at, for a more casual build using mildly modified off the shelf parts it kinda goes the other way - working with the csa available or achievable and then making the most out of it.
