Annoying news, I think I figured out why there is some oil weeping from the MLS - reviewing build photos, I forgot an alignment dowel for the head!
Obviously the head needs to come off, but I think I am also going to get another gasket just to be safe on the safe side with regards to leaks and whatnot. I will stick to stock thickness for now - leaving my compression probably a hair higher than 9.75:1.
I did have a boroscope down the cylinder wells a few days ago, wasn't looking for any P to V damage specifically but I definitely didn't see any (and don't in the photos I took), so I think I am fine on that front, but won't know for absolutely certain until I actually have the head off (my earlier clearance checks all indicated I had a comfortable amount of headroom though; I suspect I got somewhat lucky and the misalignment is minor). Very glad I caught this now, though before I went stringing everything out around town. The fastest this new motor has ever spun was 6200 RPM - for about a 10th of a second (this is based on all my accumulated data logs) and generally has almost never been higher than 5k rpm at this point, with roughly 2 hours total runtime.
Probably won't happen this weekend, I doubt I will have the gasket in hand that soon, but once I do it should be a relatively painless operation... just more coolant draining (lol). At least everything on the motor is clean and easy to take apart now. I will leave it in the engine bay and just pull the head as is.
