Hi Jerry, I just re-read the Boston Engine article; I guess I had droopy lifters. Boston Bob's advice would be to revisit the job in a week or two. As far as the TDC/engine rotation goes, I have found that rather than put a 180 degree mark on the pulley, you can get the same results with this method: Turn the engine to TDC1 and adjust #1 intake, #1e, #2i and #4e. Then I turn the engine one complete revolution bringing it around to TDC3 and adjust #3e, #3i #4i and #2e. It makes for less spinning of the engine between valves and it works out just the same. I do three valves on one side; then scoot over and do one on the other. Rotate the engine one full turn, then I can finish the second side, do up the bale and finish the last one on the other side and put that cover back on too. Another plus is that I don't always have to start at TDC1; if the engine is closer to TDC3 then I can start the pattern there just as easily.
