The fan clutch is the number one part that needs replacement every 30k or so, even if it isn't overheating it's good insurance against it and don't skimp on it. It's the most overlooked part of any cooling system and it begins the cascade of all the other cooling failures when overheating begins with these motors. You check the head gaskets by doing a simple compression test with bleed down. If a cylinder is bleeding down fast it's more than likely the head gasket. The other test is run the engine cold for 40 seconds and shut it off. If you get pressure when removing the radiator plug on top then it's a head gasket. Real simple test. If you want to go another route you can run the motor until the thermostat opens with the fill plug off, if you get bubbles making a run for it...... it's a head gasket failure.
