The Shop Manuals state that the valves might be off by .005" when cold.
So, to be sure that the valves are not always open, set them by as much as .005" wider than the normalized setting. If I am off in the wrong direction, someone will quick correct and clarify.
This is not brain surgery. Even setting them at the normal setting when cold will not cause problems, as long as you are setting the valves after 30 minutes of running.
