There are several different ways/setting to do it, even ford could not make up it's mind!
I do it in stages 30lbft, 60lbft, 90lbft, 120lbft.
Then leave for a minimum of two hours, but preferably longer, where I can I leave overnight, then retorque to 120lbft, as they will have loosened as gasket compresses.
