If the valves are good enough to reuse them. This requires a valve refacing machine. The valve refacer has a grinding wheel coolant delivery system & a chuck which holds the valve for grinding set the chuck to grind the valve face at specific angle to start the operation , align the coolant feed so that it sprays coolant on the rotating valve face. Do not take heavy cuts , if so much metal must be removed that margin is loss , discard the valve.
