Quick update

Was listening around to the exhaust today under the engine and can't tell for sure but maybe there is a leak of some sort?

What I did certainly identify that the rear bank is running much hotter than the front one. Used my infrared themometer and when compared, the temp on the front manifold was around 240F while the rear manifold was at 500F. Guess there really is a lean condition going on.

Is there anything now besides a plugging up cat that would allow that much temperature to be created?
