What is the cost to replace head gasket for 2005 Ford 6.0?

My '01 Focus just blew its head gasket. The mechanic quoted me at $1200.

At Ford Dealer ship? Yea have fun spending that kind of money. The gasket itself you can pick up for 30$ max. Find someone who knows even a little about a car, and they will prolly do it for 50$ and a six pack of beer. My friends have replaced a head gasket on a civic and its really easy if u know what your doing.
