Heres what I think about what you're saying/asking...
You need to compartmentalize the system.
It's not about the difference between .020 restriction on a small window versus a big window. Same effect there.
You have to apply everything that you've learned or think you've learned... based on your understanding of it...see each feature as a chain working together.
Understand the manifold itself.
The intake manidfold runner...make it matched all the way up to the plenum area
..but if the short turn of the intake manifold i call the flange isnt shaped right...it wont see the flow it could...and could theoretically not flow with the head.
Flow impedance aside... think about the effects on fuel suspension/re suspension and what happens to both air and fuel with A. Too small a manifold window then with B. Matched... then C. Slightly bigger..which just so happens to in particular cases help suspend/re suspend the fuel..or may be its suspend more fuel up into the central air stream. We have watched vids to see the port is wet..fuel is moving in suspension and across the surface...so imagine lifting that fuel into the stream where it will mingle with the air and light off perhaps more complete/faster..screw how I even described it.. think fuel injector.
Don't think small hole velocity , that's the ports job...think flow as much as the head and not creating dead spots where fuel and or air vorticies /whirlpool/stagnate.
It's really simple..but takes a bunch of detailed explaining that leads to the facade of over thought out idea...lets make it harder than it is with cherries on the top kinda thing.
Just make the runner as big or within. 020...or to over complicate it more... make the floor slightly bigger, straight wall perfectly aligned as well as the roof... do whatever ya I want...idk. it does make or break my day. Good luck.
