Engine won't cool off!!

Who ever came up with the idea to "take out" the thermostat, not a good idea, you need some restriction in the system otherwise the water circulates to fast and will not cool anything, and the degrees of the thermostat makes almost no difference either all that does is open temp. 160 opens sooner that a 180 but it doesn't cool the engine ANY better. I have a high flow water pump and that requires a high flow thermostat, I have a Mr. Gasket high flow the first one I had didn't open so I returned it and bought another one IMO I would test any thermostats in a pan of hot water to make sure they are in fact opening. just my .02
