After a year, I finally solved the problem of my engine getting a little too warm on the highway. Now I replaced the whole cooling system, radiator, water pump, fan (with and electric one), thermostat. No luck. Ohio YJ pointed me in the right direction to think of my fuel mixture, which was fine. Then I started to think about my timing. Well, turns out, I was misreading the timing scale (no numbers on it). As a result, my timing was very advanced. I retarded my ingnition and wow, no over heating and a much smoother idle. Only thing is I lost a little bottom end. Thank God, I didn't toast my pistons from predetonation. I checked the pistons when I did my 4.0 head swap. Anyway, thank you everyone for the input
