Noticed a couple small drops of oil on the garage floor near the expected location of the engine/trans interface, haven't been under it yet...suspect oil blowing past rear main seal at high boost 22 psi. Thinking my pcv setup is ineffective at this level and need to go GeorgeC style, venting both VC directly to atmosphere with big lines. I need to do a search as see how Atomic did his.

Thats now known as GeorgeC style? 
I had a breather on the pass side oil cap, PCV running from the PS valve cover to a T that connected to the valley cover. I drilled and tapped a 3/8" fitting there. Then the other side of the T to a vented catch can. I drilled out the DS valve cover PCV to 3/8" and added a second hole as well then Td together to the other side of the PCV.
A better way to do it would be with aftermarket valve covers that have 1" ports to vented can(s). If you dont use a can you will have oil mist go out of the filter.

Valley cover vented with -6
-10 or -12 off each cover into breather/catch cans and be done with it
Or spend good money and do a vacuum pump setup
More boost more venting and stock pcv lines arent large enough
