Since the subject is lifters, I NEED to adjust my 1961 Apache 6-235. The book says solids and gives instruction on adjusting them. It gives a lash of .006 for intake and .018 exhaust. The only thing is does not specifically say is if you adjust them running or not. It says run then engine and check the oil temperature then tighten the head and rocker shaft bolts before adjusting. I would think that this would mean the engine is off but in looking, even here, people seem to do it both off or running. I've done it both but it's been a while and I would rather do it off. Anyone have any thoughts or specific problems with doing it with the engine off? Thanks.
