I just recently done a head swap due to the #4 plug being spit out on my way to work. Fairly straight forward procedure. I had a Haynes manual, which aside from the torque values, was pretty much useless. I imagine that the factory service manual would be better. I left the intake and exhaust manifold on the head and removed them as one. Their are some bolts and nuts under the intake and exhaust that are MUCH easier to reach when you turn the head upside down. Got the head off one afternoon, took my replacement head to work the next day and cleaned it up, came home and put it back on.
