I try some PB penetrating oil overnight and then, if that doesn't work, impact wrench/drill.

I"m not sure if I try the tighten a bit then loosen routine. Could work but stripping spark plug threads in the head would be a not so good thing to do.

You gotta be careful using a breaker bar on stuff though. It removes any feel you would get from a shorter tool, and it's a distinct possibility that you'll just twist part of the plug off the heads. Then you need to get your drill and extractor out. YIKES!
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

Seafoam Deep Creep. Give the plugs a little squirt once every 4 hours for a day or two. Then use a hand impact.

If you are lucky, the plugs will come out without damaging the threads. My experience with severely stuck plugs in aluminum heads leads to one of two scenarios. First, the plug breaks. Second, the threads come out with the plug.

If the plug breaks, and is not cross-threaded, a big screwdriver shoved in the hole where the tip was will back out the remains. Lucky for you. If the plug was cross-threaded, or the threads come out with the plug, it's time to pull the head and helicoil the plug holes. Either way, not really a big deal.
If at first you don't succeed, skydiving isn't for you.
