Years ago when I was looking into putting a high efficiency water pump on my model B 1933

Do the Model A and Model B engines really like to run hot?

Do you mean like hard to keep cool?
Or do you mean it's better to run them hotter than cooler?

They run hot mostly from bad radiators or wrong ignition timing.

Engines run better at 180 than 140, if that's what you mean.

[Jim Brierley]

Normally, with everything in good condition they run too cool. A thermostat is recommended by many of us.
