Lapping valves is as old as the internal combustion engine. I've been told the owner's manual of the ModelT recommended lapping on a regular schedule, maybe once a year. A valve job at a machine shop puts a precise bevel on the valve and seat surfaces which is superior to what you can do with lapping.

When the valves are far enough gone to cause bad running, lapping is seldom the solution. At the very least the valves will likely need to be refaced (ground on the working surfaces), and you should prepare yourself and your budget for the possibility that some valves would need to be replaced.
