Lookin' good Bob!
"27,000 miles"? I would take compression numbers like that all day long! "Nasty"?

This is what "nasty" looks like after 9,300 miles!
(...why I call it "The Basketcase" )
... I’ll admit, I wasn’t really sure I wanted to know, I didn’t relish the thought of rebuilding this motor.
...For its age and having almost 27,000 miles on it...
Oh sure 2M poke a stick at the OCD guy! Nice.Hey, Bob. Good compression numbers there.
Ready for anxiety, part deux?
I'd be curious to know how much cam retardation...
Ooooooh, *now* you're interested?
Remember this?

Basically, you get the cam at *its* TDC, the overlapping valves at equal openings, or the right side cam pin pointing straight up. Then, take a pic of the rotor timing mark.
A procedure here, post #10.

The rest of that thread is enlightening...
For your valve cover o-rings, often you can just pop them out and flip them over. That presents a "new" unused side facing out and they may seal up better. I got new o-rings for mine when I was renovating it but tried the "flip" first. That was like 12 years ago and they're still sealing fine. Also, on the 3 hole covers, you can fit them any of 3 ways as they are symmetrical. Sometimes they seal up better one way than another. If you get a leaker, rotate it 120° and try that position.
Since you don't need them immediately, I would watch eBay for N.O.S. brushes. They come up all the time and can usually be found for the same price (or less) than the repops. I think the originals are better. Many times the repop brackets aren't right, a little too tall.
I'm surprised you haven't upgraded your type D tensioner to a type E w/ lock nut. That's something else I'd be watching eBay for. About the biggest issue you would have to deal with if your cam chain starts getting too stretched out would be running out of adjustment on your timing plate for the ignition.
That's probably gonna be your best bet Bob. Might want to add your comments on that knob here.I’m ready to go to the hardware store and look at grommets.

What's the OD of the metal sleeve?
Have a look here.
