anyone else have this problem??

Im having a little problem with the rear passenger side bolt on the AC compressor. Ive got it backed out as far as possible but its hitting the head and its not far enough out to pull the compressor out yet. Im taking it off to pull replace the head gaskets, and its definately not going back on after being this much trouble. Any easier way to get that bolt out? Is it possible to pull the head without pulling the compressor?
