Thanks, I have the crankshaft out and #1 piston. I'm soaking them with atf but I really doubt I'll ever get that rusted cam out or the lifters so getting the pistons out may be a waste of time but it can't hurt to try. I'm wondering how much heat I could apply to the cam bearing area and the lifters before I wreck the block, I think it's a good block yet, it still had antifreeze in it when I turned it on it's side. The pistons are aluminum so it's the rings that are stuck.
