The gaskets and harnesses are re-usable as long as they are in good condition.
I have never done it, but as I understand it the engine is started and left to idle or fast idle to operating temperature with the following parts removed from the truck.
1. Valve covers
2. CAC tubes
3. Intake tube
Everything else is connected. Ensure that no tools, rags or debris are near the engine when it is warming up.

The 42-pin harness is not actually connected to the valve cover.

You m-i-g-h-t be able to get the driver's side valve cover off by loosening the clamps on the driver's side and only removing the spider connection but I've never done it. There's no way you'll get the passenger's side cover off without removing the CAC tube. Even with removing the oil filler tube (check the o-ring if you do to see how swollen it is...you might want to spend a couple of bucks for a new one) it takes some maneuvering. If you loosen the A/C bracket and let it hang forward a little bit that helps but I've not done that. I have a lower alternator and that additional bracket complicates anything I do on that side (valve covers, EBP tube).

You might be thinking of the up-pipes, baby butt and turbo lining up issue. The CAC tubes are really quite easy. Sometimes I have to fight with the spider boot on the drivers side, but it is not hard at all.

Alright, didn't get to do this the last week or so because I got a bad cold or something. Is there any reason to not clean things before I take the covers off with brake cleaner? That's normally what we use here but we normally work on machinery without wires and other fun stuff. I've heard of people using mean green or some such.

It's way easier to clean the valve covers with them off. It's Simple Green that everyone here loves. Me included. Old toothbrush and a coupe rolls of paper towels, good tunes n a touch of patience

I would clean up around edges of valve covers & any big accumulation that might fall in to valve train during removal,I always keep air blower handy to quickly dry brake clean around sensitive wire/components.
