Really does sound like something squeaking or rubbing, like shift linkage, exhaust, that sort of thing. I don't know much about flywheels, but I wouldn't be tearing the motor apart on account of it until you know what it actually is!
Does anyone think there should be "more" oil up top? Every time I ever ran an engine without valve covers it was a smoke show! But I don't really know. I can see oil in the rockers, so they're not dry. Maybe they're just set right and I'm not used to that :-)
Can you hear it out the end of the exhaust pipe at all?

It was definitely a smoke show until I turned the idle waaaay down. I also switched to 30w oil last week because it's warming up here, so that might be part of it. I hope you're right about the noise, I'm leaning towards squeak of some sort
