The Duratec engine goes back a few years now. The first, that I was aware of, was in the '97 Ford Contour. You see one of them, you've seen them all. You might be better served to also read the Haynes for the Contour.
Aluminum heads and block. Chain driven cams.
Front engine cover does not have coolant in it. ... because water pump is on the engine rear.
The cams run bare (no bushings) in the solid cast heads. There is a definite cam cap removal/installation sequence that must be followed ... or the head will be wasted.
Front cover, chains, cams ... must be removed before access is had to all head bolts.
I have rebuilt an Duratec engine for a Mazda MPV. I have helped, overnet, a person do a head job on his MPV ... I think he felt more challenged than you might.
