I live in Phoenix where heat is a constant issue. I've found that the most expedient and probably best solution to heating issues is a Hawes Aluminum radiator. I run straight distilled water with water wetter with a 168 degree thermostat. On the hottest days, my motor will run about 195 on the hiway and may get to 205 in town. As long as I keep airflow over the radiator, it works fine. Sitting in traffic when it's hot enough to over heat the engine is not fun anyway.
