I see no difference in Coolant Temperatures with Stock Exhaust or Full Offroad SW Headers/Exhaust (I have one of each both with Ron Davis Radiators). I think the engine compartment gets hotter with Headers. That theory could result in more HOT Air around the engine and escaping under the car.
Regarding Thermostats........Just as a comparison, I have checked several
Stock Thermostats which ALL seem to open at 170 deg F as compared with
Marc Haibeck's and Jerry's 180 deg F Thermostats which open AT 180 deg F. Some run 160/165 deg F Thermostats which once the Thermostat is fully open would not make a difference on the stabilized Coolant Temperatures no matter which Thermostat you used (
A Cooler Thermostat would make a difference on how fast you get to that stabilized Coolant Temperature). This assumes the Full Open Thermostats are all of the same Coolant Flow Restriction/Flow Rate.
Jerry has the special rubber thermostat gaskets sold separately in case the thermostat gasket gets messed up during installation of thermostat.
I think we need more experiments with Radiator Cooling fan flow rates. We all have experienced trash blocking the radiators and the higher Coolant Temperature Results. We all have also experienced the effects of vehicle cruise speed on Engine Coolant Temperatures as compared to Engine Coolant Temperatures idling in traffic.
