If the head is loose (not on engine) try warming or heating it to 120-150 degrees.  The aluminum will expand quicker and more redily than the steel of the sparkplug.

spray it with PB Blaster heat it up some, and spray it again, let it cool down.  Put your socket in the freezer, heat head it up ,spray it angin and put your cold socket on and use a 3/8 impact if you have one.  If that don't bring it out,  the threads are had, so just muscle it out and fix the threads.

hi
ther is a engenering way you need a firm with a spark eroding machine they will erode all the steel away without touching the aluminium but it can get pricy to have it done, or get a special drill that cuts going anti clockwise they work normally get about half way in and the whole lot unscrews if you get a set of them start with the smallest and go up in sizes that way more chances off it givving up and comming out if not its a helicoil repair to the thread

ps use a bench drill

Are you sure it's not actually a heli-coil that's in there? Or are you confident it is the spark plug.
