I suspect either a bad O2, (your using delco right?)
Misfire (can do funky things with O2 sensors)
Valve adjustment
Try swapping the o2's and see what happens.. If your wideband was reading 16:1 and your BLMS where in the >140's I would say your definately lean, right now your just getting a false signal from somewhere.

What gets me is how weird the EASE diagnostic results are.

I sent you a PM with extra details that might help you figure out which is sending you the false signal.
BTW.
Never use anything but delco for O2 sensors. I've seen some crazy stuff from those mickey mouse Bosch o2's...

Follow-up: Tried the EASE diagnostics on a co-worker's 1985 vette and it behaved the same rendering false codes, 50, 51, 52. Also registered that the air cond. was on when it wasn't.
