I too would store it BEFORE doign any machine work. A few .010's of iron is good protection for the (after boring) new cylinder walls. I would also use a rust preventative like everyone says, on the OLD cyl walls and surfaces. Besides the chance of newly-machined surfaces rusting in storage, there's a chance you won't use the block, and machining costs would have been wasted. A clean-out, followed by inspection, documentation (photograph every surface and flaw!) and preservation would really make that thing valueable in the future -- imagine in a decade pulling out an "unknown" block and finding it inspected, with notes and measurements and photos.
