That just jogged my memory. My old boat with a Chevy 305 started running terribly so I went through all the checks, timing, fuel pressure, AND vacuum. The gauge read low around 13-17inHg and bounced around just like you described. From the chart I diagnosed just like you, loose valve guides.
Well, turns out it was a bad coil...
