5.9L Magnum recipe...

The machine shop said the bores were two or three thousandths out of round and "a lot of people get away with basic rebuilds using just a clean-up hone, but I sure as hell wouldn't do it for anything over the cheapest stock rebuild." I'm leaning towards just .020" over, since it seems like piston selection is good at that size.

F*** that guy. Prying your pocket using fear tactics is lame. The fact is, You don't need to bore it over; it's a Magnum! Those bores are super clean even at 300k taken care of. Small scratches are fine, unless the holes are wallowed out, thanks to fuel injection and metric rings, you just don't need to do it unless something is/was wrong.
