In case there was a ring installed upside down, be careful to pay attention to the pip marks or chamfers that show which way is "up". Most times these can be seen w/o removing the rings from the pistons but the pistons do need to be out of the block.
There's a slight chance that a ring could have broken and still not tore up the bore. And the bore/hone job can look OK and still not be good- it sometimes takes a close look to see the 'high and low' spots that are witness to a bore that isn't round.
