I'd rather replace the valves, but I'd rather grind off the knife edge than run with it, as long as the proper seating location can still be had on the valve head. You want the correct width seat (contact area) and it should be near the center of the valve face. I like to save old valves in case they can be made to fit antique stationary engines, etc.
