With a regrind the width at the base of the lobe gets smaller.

You do not get something for nothing. There is always a trade off.

You end up with a more aggressive lift on the side as the ramp has to 'increase' due to the reduced base diameter. It is like moving a handicapped ramp closer to the house, the angle has to get higher. So you have to lose something.

You also have to trust the guy sets things up right.

Really the cam is the heart of the engine. You need to spend the $$$ if you want things to be right. I spent the $$$ for a NOS B cam.
