I agree. I had a piston kiss a couple valves on my old motor...it left light witness marks...the exhaust valve was really bent, but the intake was hard to tell until I did the following.

Easy way to check the valves (with the heads off), remove the springs and spin the valve back ad forth with your fingers while looking at the head of the valve. If the head wobbles even the slightest bit replace the valve. Also, if you feel resistance from the valve stem (with the valve off the seat), replace the valve.
