Replaced coolant pump, replaced the thermostat, did not work. Replaced head gasket and now stuck on the road because it will not stop over heating. Drove it for thirty miles after the head gasket was changed. Radiator looks fine. Anybody have a clue? I checked cylinders they look fine.

It sounds like the radiator cooling fan are not coming on. Can you hear them working when the engine is over heating?

Here are some guides that can help:

When it's up to operating temp are both upper and lower radiator hoses too hot to touch?With the fans on are they blowing out hot air?

It sounds like you still may have exhaust gases getting into the cooling system. Lets try this test to confirm the problem.
