Remove the cap from the swirl tank, raise the rear of the car, fill the swirl tank and the recovery tank, start the motor and let it idle, keep adding coolant to the swirl tank as long as you can. When the swirl tank begins to overflow with hot coolant spilling out (indicating the thermostat has opened) twist the cap back on the the swirl tank. Let it run another 5 minutes & shut the motor off. Drop the rear end of the car. You've hopefully burped all the air from the radiator and under-car tubes but there is most likely air trapped in the highest point of the motor, i.e. the rear of the cylinder heads.

Let the engine cool enough that you feel safe to remove the swirl tank cap again. After removing the cap raise the front of the car. Start the motor and let it idle, add coolant to the swirl tank if you can. When the swirl tank begins to overflow with hot coolant spilling out (the thermostat has opened again) twist the cap back on the the swirl tank. Let it run another 5 minutes & shut the motor off. Drop the front of the car. Hopefully any air trapped in the cylinder heads has been burped.

Theoretically you've burped all the air from the system. If the car still runs hot, run through the procedure one more time.

All this "burping" is necessary because the Pantera vent system doesn't function at all. If you perform the vent system modifications I've detailed in the sticky you won't have to do all this "burping".
