Hopefully this one will not defy attempts to fix.

Sure it is something stupid that I have overlooked.

To answer some questions:

* I did better with the transfer tube, I removed it and checked the water passage. Clean as a whistle.

This vehicle underwent a complete rotisserie restoration then garaged for 15+ years. The engine and entire vehicle look brand new. Doubt there are 200 miles on it since the restoration.

*The lower hose has the pipe in it. No way it can collapse.
*Suspected new trans overheating the engine. Although I was told there is no way this could happen. I added a huge trans cooler in front of the radiator.
*I haven't opened the engine except for water pump and transfer tube check. There are no leaks that I can see around the head gasket. Doubt there is a leak into the cooling system. The coolant is too quiet in idle.
* Restrictive exhaust is possible. Can a vehicle go 80+ on the highway without missing a beat with a restricted pipe ?

There is a retired guy near me that is supposed to be a master mechanic. May let him look at it with fresh eyes.
Look at something long enough it starts to look ok.
