I read the sticky on the 2055's and I plan on buying the following, based on the advice there. Do I need all of this? Do I need anything else? I don't plan on doing the install myself. Money is not an issue, so I'm not looking for cheaper alternatives.

Without chasing each of your PNs across the internet, you don't need boot protectors, there's lots of room atleast on my 2055s, plus you're getting ceramic. 90 degree boots are neccessary, most plugs are short enough, Accel and ACDelco seem to be the exceptions. If that's the hard aluminum starter shield it may not work with your starter, has to have vertically oriented screws on the end of the motor, mine didn't. I didn't bracket my plug wires but that's more for aesthetics anyway. You will need to buy or make a shorty/header spark plug socket, I didn't have to take any length but I cut a slot about a 1/5 the diameter of the socket, resembles an O2 socket for plug access. The bolts and gaskets that come with the headers are not the best, many prefer aluminum gaskets, and some type of locking header bolt. If you're keeping the A.I.R. sys you'll probably want to get a couple of the check valves.
