Yes my low lift numbers (100-400) took a dip. That stone shattering roughed up the valve job and my Neways need new cutters to do anywhere near a half decent valve job. Now if you are asking how much more with the 2.02, 5-8 max probably. I may grab my Edelbrock Head I have sitting here with a professional 2.08 valve job and the rocker moved .300 and try a few things while I’m warmed up.
