The heads are interchangeable. The only one that is different is one from a 194 that came in early Novas. Even that would not cause overheating. Try another therm. The new ones we get now half of them are not good. There must be something with the cooling system to make it overheat like that. If it loads up with fuel before it gets hot, there is a problem with the carb. If it just acts up just when it gets hot then the carb guy is right, the fuel is perculating.
