can the valves be reused if there is a slight ridge from wearing into the seat? The valves otherwise cleaned up well and the face looks good, I lapped them and they dont leak, if it wasnt for that tiny ridge they would be perfect. The shafts show no wear and I am changing the guides
I'd take them to my buddy that has a valve grinding machine, have them turned, and THEN decide if I need new ones. Might still hand lap them into the head after that!
