So, how about a new theory - or at least an extension of an existing theory?
With the thermostat blocked open, there is constant flow of coolant so
whatever is loose in the engine and occasionally blocking the flow is
being held in place by the flow.
When the thermostat was operating normally and thus opening and closing
as the temperature of the coolant rose and fell, the flow would increase
or decrease. That permitted whatever loose item is inside the engine to
shift around and cause trougle.

I sure hope it stays that way. I drove the car like I stole it today for a
total of 90 miles in conditions ranging from stop and go city traffic to 75mph
highway travel. The temp gauge read stone cold the entire time with no
exceptions. Very interesting.

If it stays that way until you take out the copper, then it will prove the car
has had 3 bad thermostats.
So if the car had a head issue, would the temp drop from almost red zone to
normal like that by engine breaking down a hill?
BTW, I've been driving with forced open tstat now and the temp gauge reads
stone cold, even after a 15 minutes 65 mph highway drive. It will not budge.
