Ren Man - the information manual that came with my Southern Automotive engine suggests not to use a thermostat. What is actually says is to take new or used thermostat and punch out the mechanism so that there is a hole about the size of a quarter in the thermostat. This will provide sufficient water restriction flow to provide the proper cooling temp. It goes on to say that if you absolutely feel you must have a thermostat - run a 160 degree thermostat. I guess you could go to a 160 thermostat and see what temps you run. If still not satisfied, punch out the center and try that. You might call Louis at Southern if you want it from the horse's mouth. I'm sure they would give 2 minutes of free advice even if you are not a customer.
