Just as a reference, my cam calls for .026" hot. I adjusted them to .020" cold, fully warmed the engine and let it heat soak for a bit then adjusted them hot. Most were pretty close and the ones I adjusted only needed a bit of a tweak. I checked them cold and they were dead on at .020" again. It might be a bit of a pain to go back and forth like that, but the important thing is that you make sure your "feel" of the gauge you use is the same on all of the valves, and you check them a couple of times both cold and hot and record your findings....After that it's just a matter of the "tweaks" from time to time!
