if it was overheating before the head gaskets were replaced then it probably wasn't it. Best thing to do as you probably don't have any leaks is to disconnect the fans and check the radiator. do this after it overheats and try placing your hand in different spots all over. If you feel any cold spots, then your radiator is bad. It should feel the same temp by hand all over. if you see any loose fins or greenish color ones you will need either a recore or a new one..
