With a flow bench you can watch air flow, add a wet flow bench then you realize there are so many factors involved it is mind boggling. Valve angles, valve shapes matter.
Physics will get you close but nothing like real world testing. Just like the texture issue in intake runners and heads, might not mean as much as you think when you add fuel to the air flow.
Don't get me wrong, Physics always give a good base, real world gets these top guys to the top.

The laws of physics show them self in many ways. Next time you talk with your local air flow expert. Ask him if he has ever changed a ports design because it did not sound right?
