I changed the head gasket, fan clutch, coolant, thermostat and sensor, ambient air sensor, water pump, new BMW coolant and changed the vacuum hose, but the temperature still gets high.

This is inside of the radiator please check this guide out about half way down.

and I would see if the head is cracked by doing a chemical test here:
