I read all the previous posts, and one suggested a High Flow thermostat, I have a 2 row aluminum from Jegs a high flow, Flowcooler pump, high flow 185* MR. Gasket thermostat and I have a flex fan direct drive, I have cast iron stock heads, water wetter, and my engine NOW will not get to operating temp, so I am installing a clutch fan, long story short I put all this stuff into my car cause it was overheating and now it wont get hot enough, so did you install a high flow thermostat??
