In distrib2, is that oil on the "blade" and underside of dist? If so, the dist O=ring may be tired.
You appear to have good oil leak around the back manifiold studs. The upper stud actually goes thru to inside of rocker chamber and oil can migrate down threads. I suspect oil is migrating from there to lower pipe. Also, run a paper towel along the head just below the rocker cover seam (at least above #3 and 4 plugs to see if that gasket is the culprit.
