Yes, I have an aftermarket Autometer water temp gauge and sensor which I installed into the head (I iinstalled it where the allen head bolt on the rear of the passenger side head used to be). It was running in the 170-180 range the whole time.

Fuel pressure or water temp. Did you have a water temp guage installed, a manual one? You may have air in the top end and it was overheating.

Based on the performance description, that would be my guess.
