I've got a spark plug that appears to be seized into the head of my Golf (MK2, 8V GTI, PB engine). The other 3 came out quite happily with an 8 inch bar using a surface drive socket. I'm loathe to apply a lot of force for fear of it shearing off in the head, but the plugs do need changing as due to standing with less than brilliant valve stem seals, there's a fair bit of oil fouling.

Is there anything I can do other than keep spraying it with plus gas? Can I use differential expansion (blow torch or freeze spray)? Would I be absolutely insane to try a rattle gun? If I recall correctly, it's an alloy head, and they're not taper fit plugs.

I can also promise you that I won't be grateful for replies informing me that a) I should've greased the threads when I put them in - it wasn't me, honest and b) I should've pulled the plugs when I bought the car, because I bloody well know I should have...
Well, they aren't taper fit, and it is an alloy head.
