One other thing that can affect temps is running too lean. I learned that the hard way and burned some valves. It turned out the plug on the back of the carburetor that capped the port for the power brakes (my car didn't have power brakes) was cracked and caused a huge vacuum leak. The engine ran well, and the fuel economy was good (19mpg highway). I did notice that sometimes the high temp idiot light would come on. Anyway, after driving on a rebuilt engine that way for 2 years, it burned some valves. Only then did I look at the plugs and they were way too light.
