As for why you over heated maybe both of your fans quit working or your thermostat got jammed. Also possible you have a crack in one of your rad hoses. There are a couple posabilities but I don't think you cracked your head gasket or did any damage to your motor from what you described. I have seen these motors take a sh^t kicking in my day with no issues.
Removing the clutch fan and not replacing it with an electric alternate is not a mod, it's just removing the first stage of engine cooling. The aux fan comes on if that is inadequate or the A/C is on.
