There will be a steady state at some point. You would like it lower. Don"t underestimate the headgasket component of channeling coolant flow. In the TR4 motor i made the coolant holes different than original to allow the mass flow of water to occur from the rear of the motor forward. I also put a pressure gauge on my coolant. If the pressure is too low it will not cool as efficiently either. I don"t know what the coolant dwell time with in the head needs to be to in order to adsorb the heat generated. Nor the dwell time in the radiator.
