Two things to remember now that I've written this post. One, the valve springs are conical. Put them in the right way. Two, the cams do not need to be removed, just use a big screwdriver to pry out the followers against the spring pressure. Three, use grease to try and hold the keepers to the valve. Four, plug your oil galleys down to the crankcase (I remembered this obviously). Fifth, put a rag in the spark plug bore. I dropped the a keeper down into the plug bore and into the combustion chamber. Dumbass move for sure. I was able to easily fish it out with a long magnet on a bendable wire but still. Kind of a tense few minutes. Sixth, be sure you have the engine braced when you go to put air pressure to the cylinders. I ran it with about 60psi and while it held the valve up nice and tight, it was really putting a lot of pressure on the breaker bar holding the crank. Worked fine though once i got going. Once again, this did not help with the pinging. So I was still hunting and we were decently into May at this point.
