I've done many a valve job on cars, trucks tractors n such. If the valves are not bent then I hand lap them with a grinding compound. Used to use a suction cup style handle that stuck on the valve, rotate back n forth, lift and rotate, long process. Then I discovered variable speed reversable drills I now use that with lapping compound, back and forth, lift and turn, trick is not to go to fast and cause grinding compound to flare. Works very well with practise.
