Any way you can take a picture down the tube and see if there is any damage to the head?
I thought about this and I should have done it just for this thread.
But I need the truck tomorrow so I angrily put everything back together and went around the block. Figures, not a single issue. No low idle, no stalling out, full power.
My reasoning for doing the one plug - is that I think all 8 are original, and the power drop that happens intermittently I am thinking could be the #7 plug electrode worn right down to nothing causing it? I just wanted to see if it produced any results - but the joke is on me!
This is my punishment for 25+ years of owning and working on imports I think, haha.
Trust me, the head of this plug is F*ked. I almost hammered a 9/16 on it but was fearful of making it even worse.
GET THIS - The 5/8 socket I just bought - got stuck on the plug....had to clamp on some vise grips, and use a long breaker bar to get it out of the hole!
Now this is counter-intuitive! IF it's gripping so tight that the socket is stuck....how the hell is it not turning out?

Reason: two more sentences
Just throwing it out there, removing the intake manifold changes the spark plug game. It's a pita, yes but from the sounds of your issues it may be worth it.
Better view...
More leverage...
Better use of tools...
One other idea would be to try and break it loose when the motor is warm. Don't extract it all the way (at least, I wouldn't) but at least try and crack it loose.
Another last ditch option is to take that sears socket you don't care about and pack in some jb weld (NOT A TON, just enough to fill the gap between the plug threads and the socket) and let it harden a full 24hrs (or maybe a bit longer since its been cold (and friggen snowy)).
Just know this, if you put too much jb weld on there and it fuses to the head on you will have a new problem that will be worse than your current issue
If you look, the first 1/8" dont even contact due to shape.
I havent had this problem on spark plug, but have on a few others, mostly small stuff, and it works to put socket on enough good metal. Depends on if the spark plug flats are flush or elevated a tad though
Flange bolts with low heads usually benefit from this, flanged hex head cap screws
I don't have experience with those specifically, but I have a similar set made by Craftsman. I will tell you that it had enough grip to grab onto a round head bolt... and enough grip that I busted the bolt (for the tailgate cable). I wish I had heard of Kroil when I tackled this job... would have been much easier.
