At the cam face it lifts the same - NOT at the valve tip which is where the air enters. This debate occured on Corral too, and Buddy Rawls mocked up both with a dial indictor and degree wheel on an engine that he uses to check his cams and proved that the duration at the valve is longer. I forget how many degrees were added, but if your after every last deatail to make power - this is one that works.
