Intake Manifold Reseal - Decent this parts list?

My car has been rough recently and the economy gauge has been 3/4 of the way pegged to the left. I checked the timing and it is off by about 10-15 degrees. Unplugging the EZL resulted in it being off 5 degrees. I decided to do a smoke test to see of there was a major vacuum leak. Some smoke came out from below the intake manifold area. I guess its time to go in and change out the applicable gaskets while I'm in there. How does this parts list sound? Any of them redundant? The car has newer injectors.

Intake Gasket Right - 117-141-25-80
Intake Gasket Left - 117-141-24-80
Donut Seal Rings x 8 - 117-140-02-65-64
Throttle Housing Gasket - 117-141-26-80
AFM Boot - 116-140-06-18 (Is this even worth changing?)
Exhaust Gas Recirculation to Intake Manifold Lower Part - 117-142-04-80
Fuel Injector Seals - 116-070-00-77
Fuel Injector Nozzles - 117-070-04-55 (Worth changing?)
Fuel Injector Nozzle Seals - 009-997-10-48 (Worth changing?)
Fuel Distributor to Air-Flow sensor seal - 004-997-07-48
Air distribution hose x2 - 1160942582 (worth changing?)
air distributor connection x2 -1020940212 (worth changing?)
air distributor plug x2 - 1169971286 (worth changing?)

My headgasket is leaking oil on the drivers side. I'm tempted to change it since I am pulling the intake but after reading about having to possibly helicoil the block, I don't want to touch it.

Regarding the head gasket leak, I know one person who loosened each head bolt one at a time in the order they would normally be torqued and retorqued each bolt. This took care of his leak.

I wish I had remembered this trick recently on my Dad's M103. Unfortunately I pulled the head and now the car has been sitting for months.

Anyway, the driver's side head is seeping on my car, too, and I think before I go to all the work some day, I'll definitely try the retorque idea first. Seems to me the only possible downsides are the leak continues or you possibly strip some threads and have to do the job anyway.

I think what I'm hoping is that you'll try it!
