Brent,
On a 50 hour engine, I would probably be inclined to leave the rings alone. As long as you were not haveing any type of oil problems, they should be fine. Rings are easily available if you decide to change them You can get them from GM, Speed Pro and Hastings.
I would be more concerned about the condition of the connecting rods if it hurt the rod bearings. Also, make sure the piston pins are not too tight in the pistons, that can cause rod bearing problems.

Hastings makes a replacement ring for the metric style J/E pistons,expect to pay around 200$ for them,Smitty

I bought some from a local speed shop 4 years ago for a guys 502 I was rebuilding,they are in the hastings catalog,just find any shop that sells hastings products. Hastings is a common company that sells parts,sorta like melling or felpro,any performance shop should be able to look it up for you,Smitty
