"You do have to make up the difference in the slightly shorter total cam lobe."

And that's why I still stand by my statement that the original specs can't be in a reground cam.
Either the lift or duration will have to be changed.
Actually I need to add a third parameter to this to be accurate, and that is valve opening to piston position. So, if you have a reground cam you can't have the same degree for engine cam timing and the same lift and dwell as original factory specs.
