watch this vid, it shows how to remove the lim, plus lifters but you don't need to go that far. you can also take lots of pictures along the way and tag wires and hoses so you don't forget where things go. i wouldn't pay a grand to do this job myself, but thats me. or try a local shop, dealers just rape you.
