If you have your stock cam ground for more aggressive ramps/lift your base circle has to change. I'd expect you'll see a change of 20 to 30 thousandths after you get through with it.

You'll need to re-shim, you machinist should have the correct tool/spare shims to make this fairly simple.

I am doing the lifters and cam at the same time.

Jonathon, you know how much lifters would be? I no longer work at Precision... conflict of egos.
