that all depends on your motor and your timing. also are you wondering about the valves hitting the piston right? with high lift cams you also have to be carefull of valve to valve contact as well.

You can run long duration and moderate lift cams with oversized valves. The best thing is to get adjustable time gears and a timing wheel to properly time the cams.
