Anyone have an opinion on valve lapping? I've heard some people say it is an outdated process and a waste of time. I'm cleaning up some eddie heads that are about 10 years old, but the valves look to be in good condition. I cleaned them up with brake clean and some steal wool. They look pretty good, but i would happily do the labor involved with lapping if it will benefit- though if it is a waste of time I won't bother.
