Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

we had a mechanic at the dealership that would "hone" the cylinders oversize. not sure how large, maybe .005"? they were tight, his break in procudure was to start the engine, let it run till it started slowing down. shut it off, cool down and THEN add coolant! glad it wasn't my car...don't remember it coming back though.
