My question would be why is it puking out coolant at 198 degrees when a stock one doesnt even get the warning light on untill 220 degrees? the factory engine runs between 192 - 205 degrees and the thermostat isn't fully open untill 119 degrees.

I've wondered that myself. There is no indication, blackening of coolant or bubbling in degas bottle to indicate a head gasket issue. Temperature gauge error? Unloaded, there is no issue. Add 4000 pounds TC, issue.
