I thing with camshafts and valve springs. The more duration you use the more lift you can use without changing springs. A short duration high lift cam opens and closes the valve great distances very quickly. Higher spring pressure for this, meaning new springs.

So being that the beet cam has the most duration I would suspect it has the highest lift since the is no aftermarket springs for any camshaft out there.

We will find out next week anyway.
