Anytime you have a valve hit a piston there is great concern to whether it damaged the piston or not. It could damage it at any RPM. My concern is why did the valve stop and hit the piston. There are alot of factors that may have caused this so it would be hard to point to just one thing right now. You may want to get ahold of some of the car clubs in your area and ask them for some good machine shops or stop a car show and ask. If you are in the Hampton Roads are in VA I could help you but not many people seem to on the boards from around here. Good Luck.
