Put new plugs in an '04 5.4 (all plugs thankfully came out intact) and all back together. I did use a very thin coat of anti-seize on the electrode shield as per the TSB (none near electrode tip, none on seat or threads).

I used the Permatex stuff found at the counter of most auto stores (This stuff). I now see that this stuff is a mix of aluminum, copper and graphite. No nickel in it at all. The TSB specifically states to use nickel anti-seize. Never knew their were different ones.

It seems the regular stuff is good for up to 1600°F. The nickel stuff is good up to 2400°F and is for extreme pressure and temperature. From what I have read, the anti-seize kind of "burns off" during combustion, and the nickel based stuff will leave a thin coating of nickel on the electrode, preventing carbon from building up.

Is using a non-nickel anti seize going to cause any issue? I am not so much concerned about future plug removal (I am sure the truck will be gone by that time) as I am about this causing an issue with plug fouling. Will the stuff I put on just burn off? Will it foul the plugs? I really don't want to take them back out, but will if I have to.

Alum and copper don't get along at all . Add heat and they act up . The tip needs to keep the compound on it at the higher heat . I know my nickle stuff works on my third set of plugs . Got it from amazon .
I would not take a chance for long .
Torque those plugs in too .

Thanks. I thought I was over thinking this.

Truck starts and runs much better than before, so I am not going to worry about it.

You are fine. I sometimes over-think things too.
