After many years of adjusting valves--on everything from farm tractors to top fuelers--the most accurate setting is atained with the engine NOT RUNNING, and set at what ever temperature that you use

On the top fueler, funny car(Keeling&Clayton California Charger) and pro-stockers, we had a cold setting for assembling the engine and we final adjusted after warm-up-- Anyone should be able to run the valves on a V-8 OHV engine in less than 5 minutes--------if anything has moved significantly you have a problem and the valve adjusting exercise turns into a bigger job.
