The LT1 is one tough engine to tune up considering my skill set.

What AFPR was it? I've got ordered a TPiS AFPR.
I have heard the vacuum nipple thing coming loose on these. I believe that nipple is just screwed in. I plan to remove that and tighten it down with some blue thread lock on the threads.
I've also read it is a good idea to put blue thread lock on the bolts that bolt the hat down on the regulator. Before I put the plenum back on. I plan to turn the key "on" and raise the pressure up to something like 55 psi to make sure the regulator doesn't leak before I put it all back together.

It's not really that tough. Yes there are couple of plugs that require some true manual dexterity. The real secret is to not be in hurry. To change the wires, if you go ahead and remove all of the things in your way first, mainly the belt tensioner, the ac/alternator assembly, the asr or at least the plastic cover and emission hoses, you have a pretty straight shot at most everything. While it seems like a real pia, it just takes time. It takes more time getting to the plugs and wires than it does to actually change them. The good side of this, is you get to clean parts of the engine bay you normally can't reach.

Connect a vacuum gauge to the engine. With it idling see if the needle holds steady. You'll be looking for a possible vacuum leak.
On a very dark night, check carefully for any spark arcing to ground. Look VERY carefully since some are hard to see.
