From my Ford Manual:
Disconnect the heater water hoses (18472) from the heater core (18476), and plug the heater water hoses.
For easier access, remove the glove compartment.
From inside the passenger compartment, remove the seven screws which attach the heater core cover to the heater air plenum chamber. It will be necessary to move a "RABS" module out of the way on F-Series prior to removing the cover.
Disconnect the vacuum source. Leave the vacuum hose harness attached to the cover. Remove the cover.

The only thing I would add is to cover the floor inside the cab (passengers side only) with plastic and/or a towel. Every time I have pulled a heater core it always drips and/or spills coolant inside the cab as I'm pulling it out. No a hard job at all.
