The situation:
My 1000 my rebuilt 12v has a very slow but steady leak. My best guess is something behind the adapter plate (follow arrows in pics). Its definitely not the #6 valve cover. It’s got 10qts of oil but reads over on the dipstick though.

Questions:
  1. Is this oil pan dent deep enough to make 10qt of oil read to full?
  2. Would being overfilled cause the rear main to leak?
  3. If 1&2 are true, would running 9-9.5qts of oil “fix” my leak?

That dent is no enough to cause a fill problem.
Have a good look at the tappet cover (sideplate), the seals on those bolts tend to loosen and the gasket leaks.

Agree that dent isn't bad enough to cause an issue. If it's leaking out back then you likely have a bad crank seal or maybe getting around the oil pan gasket. Tappet cover is also a good leak area but that one should be easy to spot.
