The combination of all three components led to valves opening and closing at the wrong time, or not opening at all. Resulted in almost as much flow back out of the carb as was going in through the carb

You give me too much credit! I'm not ready to attack a full engine at this point, so i only tore her down far enough to replace what I knew i needed to. At some point i'm sure i'll have to address the heads and cylinders in a real way, but for now i'm ok with how they looked from what I could see from the crank galley.

My guy, old school dude who owns and operates the auto parts store, has me running a high-zinc oil designed for engines of this age. He called it a "performance engine oil" which would be a stretch to use the word "performance" for anything on my truck!
