Running without a thermostat ok?

I have heard people argue both ways. Personally I got tired of the cheap parts store thermostats freezing up every single year after the car sat all winter. I took a thermostat and gutted the spring and diaphragm, but still run the housing to restrict enough water to somewhat simulate the thermostat being open. Been working for me just fine. Car seems to run at 170 despite ambient temp. Thats one opinion. Hope it helps.
