It's worked for me in the past. The only other thing I can think of is to run it for a little and then try to pull it while the block is warmed up a little.

If it's that tight, it's most likely cross-threaded. Be ready to do a HeliCoil job on it. Not all that nasty, use some grease on the tap to catch the chips.

PB Blaster in the hole won't hurt.

Us a small dab of anti-seize on the threads of the new plugs.
