I set a stock C-code 289's valves via the three-crank-rotations method in Tom Monroe's book. Engine runs OK but I need to do a final adjust on the valves. Do I back off each one until it begins to lightly clatter and then go 1/2 or 3/4 of a turn to tighten? What's best? Does this need to be done in any sort of sequence or can I just go right down the line?
Also, the exhaust makes alot of noise, even with the muffler in place. Would this occur if the valves were not yet set correctly?
