Thanks to all who replied. Hi Dave! I have a 235 that the mechanic who overhauled it, adjusted the valves before the engine every ran, and when I put it in the truck, it ran great! I have been told that a good mechanic will adjust them slightly loose. I have never done this before, and I appeciate the tips!
