Just make sure you blow out the plug well, before removal, or all that dirt will be in your motor.
On a side note, I see it was mentioned, Is this the 3valve motor, if so follow the ford procedure to a tee to remove the plugs, and leave them soak two days if needed. If one of those plugs break, and you don't have the removal tool, you will wish you let someone else do your plugs.
If it is not the 3valve then removal is the same as most other engines.
