Could be, how about the radiator? Does it look like it's 40 years old, could be plugged and lot allowing good coolant flow.
You said you don't like the Hayden clutch because it's so noisy. You didn't get a severe duty clutch did you? They are noisy and all you should need is the heavy duty.
Try making the idle mixture a little richer. Turn the adjustment screws counter clockwise at least 1/2 turn, see if the idle temp stays closer to driving temp.
Also, are you sure your temp gauge is accurate? Does your buddy have an infrared thermometer to check the engine temp.
