Radiator installed. Took for drive, no leaks, temp gauge goes up then down a tad after thermostat opens up just as it should. Heat is good. Blasts out nice and hot inside the cab. Ran for about 10 miles with heater on, pulled over and opened hood to check. NO leaks all is good.
Ran the rest of the way home with A/C on to really put engine under a load and all was STILL well.
So it WAS a bad radiator.
I now have a new heater core, thermostat and water pump and radiator within last 10k miles so I think my cooling system is good to go for at least another 100K !
For any of you reading this I will say that the Suburban is absolutely the BEST vehicle I've ever owned. Besides the normal stuff like alternator, starter, water pump and now radiator I've had no MAJOR issues at all. It still starts, idles, runs, shifts and rides awesome at 160k. The engine is smooth as silk and still perfectly quiet.
ISSUE SOLVED !
