It's not too hard of a job to do. Before you start tearing things apart, go to your preferred parts dealer and get a head gasket set. You'll probably have to order it, but it's worth it. It'll have all of the gaskets you need plus quite a few that you won't need... and it's cheaper than buying everything individually. It also has new valve stem seals.
After you get the head off, take it to a machine shop. They can shave it down if it's warped, check it for cracks, make sure your valves are seated properly and put in your valve stem seals. Plus it will be all nice and clean when they're done. I had my 2.5's head worked about 2 weeks ago for around 85 bucks. I had it back in two days.
Get everything you need for an oil change and a couple of gallons of antifreeze and your set.
x2 on the chilton's or haynes manual. There's a sequence to torque down your head bolts.
Also, when your refilling your radiator, remove the heater hose thats next to the thermostat housing. It helps eliminate that horrible air bubble in your system. When antifreeze starts to come out of the opening at the thermostat housing, put the heater hose back on and burp your radiator.
I'm sure I've forgotten something....
