I watched it. Had he said it was all about air flow management I wouldn’t disagree at all. But saying you would never use a head bigger than 200 CC’s on a SBC is silly. 200 CC’s doesn’t tell you much about the port or its shape.
At the end of the day, you can’t violate the laws of physics and think you won. Not all “big” ports are bad and not all “small” ports are bad.
