When I did mine it was an absolute pain to get the air out of the heater matrix. I found the best method was to raise the front of the car up so that the radiator cap was above the air bleed valve. You can then force coolant into the heater matrix and the air eventually comes out of the radiator. It takes a while, a lot of massaging coolant hoses and a lot of cursing to get done.
