You have a solid lifter cam meant for a 1/4 - 3/8 mile banked oval. 3200-7200 RPM range. .500 valve lift on intake and exhaust. 300 degree ADV duration. .246 .050 duration and 112 lobe center.
If you mean too much lift because the valve might hit the piston, there is only one way to know for sure and that is to check it.
It might be too much for the street. I would call Isky and ask them their opinion. 323.770.0930
