All you fellas must be commended, as you all have great suggestions.
Getting into the engine compartment again, here is one thing we came across.One previous mechanic had installed a new ballast resistor. In addition, the plug on the driver side had its male keyway broken off. It prevents the plug from being installed upside down. He installed it upside down!
I noticed signs of arching across one spade of the ballast resistor. I took the Ballast resistor off and found the internal connection intermittant. Very surprized the car ran at all. A new resistor has been installed and the plug properly attached. I do not yet know what electronic components may be damaged because of this stupid error. We're taking it slow and rechecking everything. 
Someone had asked why the head was replaced. I believe the young mechanic who installed the resistor plug upside down, caused the serious driveability problem. His inability or anyone else's, to then diagnose the driveability issue, a valve job needed was declared. It was less costly to order a reman head, than to spend more labor $$ for a valve job. In hind sight, I doubt it was required.
Grannies Volare has only 54,000 miles on it. Granny loved this car bought new in 78. When gramps was changing oil, he left greasy fingers prints on the vinyl roof while getting in the car, (which did not come off)! Granny made gramps pay for a new vinyl roof. That was 15 years ago. The car is in miraculious condition. In our meticulous review of the engine compartment, we found this know it all young mechanic had used a fine threaded metric bolt in a regular threaded hole. Of course this did some thread damage. The hole had to be tapped. Its lack of attention to details that result in problems. I have not yet got things back together & cannot yet say if driveability has been resolved, but we are on track to getting to the bottom of these issues. The engine is very difficult to turn over by hand and Cold valve lash has been found to be set to tight. I have learned never trust anything a mechanic says. The only sure fire way is to do all the work yourself. As a disabled Veteran, this is not possible for me. A good friend has finally come to my aid. He is willing to take his time. My appreciation for MOPAR from the good old days, (though sometimes troubling), never dies. I'll keep you posted.
