It also helps to park the car on a slope with the radiator pointing up. This helps to get any air out of the heater core.

I would take the top hose off the radiator, pull it up as far as it will go without kinking and fill it with water until water comes up to the level of the hose. When I use this method of filling the block, I never have air issues..
