It's my routine. Always has been. Doing it someone else's way may work fine. Never said it was wrong. I don't typically open the engine up at the track. This is shop maintenance. Once a fresh engine has settled down, I don't do it every week. Warm it up, throw a light on it to make sure nothing has moved. Check the trans. Run the valves. Look everything over. I can do the valves in a few minutes if nothing's out of whack. Upside? IDK. Taking care of all this at once. No fudge factors to forget.
