If you re-ring the motor you NEED to give the cylinders a hone. If you don't the rings will NOT seat. Double check your piston to wall clearance before honing cause the bores maybe worn. If they are worn then a new hone will enlarge them even more with piston rock/slap as a result. Not good!

Probably should talk to a good machinist, have him look at the cylinders if possible. Today's moly rings work well on a smooth wall. Standard steel rings might need a quick hone. If you can still see the hone marks in the cylinders, and you might, you might have a very good surface for the moly rings.

Lots of good info here:

Looks like you should use a hone or glaze breaker to insure proper break in of the rings.

I echo the comments of the others, you need to hone the cylinders in order for the rings to seat properly. It is a must.
