That’s one of the reasons I use a 4.015 bore adapter for testing even with 2.08 valves. In my head I feel with shortturn shaping you can dictate the direction that most of the airflow is going. Probing the runner for airspeed can back this theory up. Think 3D and check each runner from every angle.

Near the end of the video he shows the narrow quench pad that he left on the shrouded side of the intake valve. He left it there to keep velocity up in that area instead of unshrouding the valve and increasing flow (which he said also decreased the velocity in that area of the valve). Fascinating.
