    It might be worth while to try using a pistol type thermometer, where you can point it close to the head and see what the temperature is. You may be able to hire or get the loan of one.
    It may also be worth running the motor without the thermostat and watching and feeling the discharge water to see how hot it gets.
    Another method, which is shown in the workshop manuals of the 1960s, was to use two thermomelt sticks. The higher temperature one melted if the motor was running too hot.
