Wave strength in racing engines

Multi EMC winner John Kaase show how ludicrously strong the tuning waves are in a racing engine. And you wonder why it's so hard to get stable MAP readings with IR.
One of his EMC tricks.
Old heads have notoriously bad short side radius, ie they are too short for good flow. So he added a 1" block to the head and lowered the piston 1" so he could grind a much better port. The port is practically a downdraught port.
In EMC you get points for making power between 0-6500rpm max, and they typically make 300hp@2500rpm and 700@6500rpm.
