Is the exterior of the radiator clean?
Is the fan belt properly adjusted?
Use a IR Thermometer to check the engine outlet temp, at the low side, of the thermostat housings on each cly head. Temps should be close. If a big difference suspect a thermostat failure.
Was the oil pressure lower than expected with the elevated temps? If not the water temp gage/sensor is suspect.
