the idea of having thermostats is to create a temperature difference between the engine block and the radiator ... this temp. difference siphons the coolant around .. hot water rises, like in a home hot water system ... If you remove the thermostats, the whole system is almost at the same temp., and you lose the thermo-syphon effect . Many veteran cars have no water pump at all ...they soley rely on the thermo-syphon thing to circulate the coolant around.

Those SV Ford lumps are HOT motors ,it's a design thing ,the exhaust gas ports are such that the motor runs hotter than it should.
