Removing a stripped bolt

[cookster50]

I've blasted it with PB Blaster. The thread is fine, the head is starting to get rounded. I don't have room to get a hammer in there. Guy at work said I might have to file down the head a little in order to get the smaller sized bolt extracter on it. As for removing a lot of stuff to make room, it's all the pulleys for the serpentine belt that are in the way, not sure how to remove those. I know you can get the pulley off the power steering pump assembly, just don't know yet if a pulley puller could even fit in the space I have to work with.
