Mike Meziere buys CNC machines from us that he makes these pumps with, I have 2 of his pumps on different engines. He and I had a long discussion about this. He felt it was hard on the pump motor when the thermostat was closed. He felt there was no need to run a thermostat. I run a gutted Thermostat as a restrictor ring on my 66. Car runs about 180deg when I drive it on the road with a block filled to the bottom of the freeze plugs.
