On the timing, in your driveway just run it up to the same RPM you are at on the highway when it is getting hot & see what you get with your dialback or make some marks. 0.0632683" around the circumference is 1 degree on the dampener or can use the tab as a ruler. 2&1/4 (2.246") is 35.5 deg which should get you close to what you have tho the can will kick it higher above that
This made me think of something, can you duplicate the overheating in 1st or 2nd gear if you hold it at the same rpm as you run at highway speeds? If the engine doesn't heat up in the lower gears this would seem to eliminate the water pump and pulley possibilities. I would be interested to know the results of that.
