if it's at a pullapart, you may be able to borrow one of their cranes to aid in removal. if not, take everything off the head first to make it easier to lift. them things are not light.
how good is the car? can you get the whole thing?
I would pull the injectors (carefull, pop the wrench, don't steady pull, or the PC Rings may come out) and see if you see any rust on the injectors. rust = water in the head... possible cracked head. remote on the 617, but not impossible.
