did you take the power steering bracket off. Can't recall for sure on that engine, but think it joins the block and head. Also, there should be tabs on the corners of the head for inserting a flat screwdriver to pry the head up. If you get a blade in those and it still won't budge, you have something still bolted somewhere. Needless to say if you blew your engine it could be any of a number of things, obviously a valve could be sticking through a piston or Lord knows what...
