Well, I got it done, took most of the afternoon at the shop. There is one bolt that does not clear the turbo so I ended up cutting the head off and backing the rest out with pliers, I replaced it with an allen head capscrew that would clear. Other than that, all the fuel and coolant lines in the valley need to be disconnected and swung out of the way. I would not do this in your garage unless you have a lot of tools. I was in a full auto shop and still had to get creative a few times.
