No torquing required at all. Maybe the anti seize keeps my threads clean..
This is just how I been doing it for the last 33 years. You can do it however you see it fit for you. No problemo :-)

My method as well. I replace the plugs every 25,000 miles (NGK BKR5EKB-11). Anti-seize and hand tighten quite snuggly once I feel the crush washer make contact. No issue in 21+ years & 517,800 miles.

I'll give it a shot when it's hot instead of warm and report back.

Did some more digging. Denso's website says torque spec is 15-22 ft-lb in an aluminum head or to do the 1/4-1/2 turn past contact if you don't have a torque wrench. FSM says 13 ft-lb. Denso also doesn't say to not use anti-seize like NGK. They just say to reduce torque spec by 30% if using anti-seize. So I think I might pull them all back out once I get this stuck one out, put a light coating of copper anti-seize on them, and reinstall to 9 ft-lb (109 in-lb). Wish I would have done all this digging before I installed them the first time and crushed all the washers but it probably doesn't matter that much.

This is all a part of the learning experience. And from this point forward you'll always know what to do and can even lend assistance to others doing it. All a part of the game!

Got it out! Got back from a drive and gave it another shot. It didn't come out easily and I was holding my breath the while time but I just kept working it back and forth with quarter turns.
Hopefully about 45 minutes with the hood up is long enough for it to cool back down before I install the new one because I need to head back out in a bit.

Funny thing is I've been working on cars casually for like 25 years and just never ran into a stuck plug before.

Just wait till you come across a cross threaded spark plug. Then you really have fun. 
Is it only one spark plug that's snug or several of them?

It was the entire passenger bank. The driver side came out easily but interestingly enough, that side also looked like the valve cover gasket had been replaced while the passenger side looked original.

The valve train on that side was also noticably more varnished.

I picked up a one-owner '02 for my daughter in June 2020 with 199,000 on the clock. Always dealer serviced.
When I test drove it, the truck could barely reach highway speeds and bucked at different throttle positions. The deal was way too good to pass up, so I took a chance that it was something easy and not the tranny.
This is what I found when I pulled the plugs:

I installed new NGK plugs and three new plug wires from Toyota. Ran perfect.....

That's nothing I had one that had original spark plugs in at 215k. The spark plug electrode broke off and is stuck In the piston surface. The engine would misfire as the ignition would cause the porclin to chatter as nothing was holding still anymore and half the center of the plug would move every fire on that cylinder.

Mine looked marginally better than that and the dielectric grease on the electrodes had turned into the mosquito resin from Jurassic Park.
