The LS1 & LS6 have to thin of liners to go the standard .030 over. Now a .0001 hone is sandard and you can go several hones of that much w/no issue using the stock bore size pistons. The liners in the LS blocks rarely show much of any wear at 100, 150, 200k plus miles when syn oil is used so rarely would we ever need to bore them. Only a hone to remove the hard glos and lay down a cross hatch so the new rings will seat properly. In fact, in almost every LS motor I tear down the original cross hatch is still visable and no wear ridge such as the old school motors had showing just how tuff these motors are.

Ok that is what I thought. You confused me there for a while when you mentioned that you could not safely bore an LS and when the original question was to a thousandth I put both together.
