just because it looks good doesn't mean there's not a loss in compression. if there's a problem in the cylinder then you waited way too long. if all is fine, which is good and means you caught it at the right time, then get some new rings and slap it all back together. if you have a service manual, you can check the specs and mic the piston to make sure it's in spec and measure the cylinder bore to make sure it's in spec.
basically from what you've said, get some new rings and get the cylinders honed, slap it together, it should be golden.
