Check the timing. I also suggest a Milodon 160 degree thermostat. The thing is costly ($15 from Jegs) but the motor will run cooler. I also suggest checking the fan clutch. Like Ed said, have someone shut off the car with you standing in view of the fan. If you see it spinning with ease after the car is shut off, then the clutch needs to be rebuilt or replaced.
