LSA Rings?

I bought a used LSA short block out of an '09 CTS-V to replace the LS6 that was in my '04 CTS-V (which has a cracked block.) I'd like to "freshen" the short block with new bearings and rings since it's out and I'm taking it apart to clean and inspect everything anyway.

I don't see any ring "kits" available from the usual suppliers. Should I buy individual rings (1.5mm top, 1.2mm 2nd and 2.0mm oil), if so what would be recommended? Alternately, should I just put a new set of stock rings from GM back in?

The motor will have a stock LSA bottom end, CNC's heads, upgraded cam/valve train and current plan is to re-use the Magnuson MP112 from my LS6 on top.

Don't forget to hone the cylinders.

I would call around and see what different manufacturers offer and compare to the stock rings. The stock rings are nice, but nothing special so I wouldn't pay for GM rings if they're expensive. Total Seal, Mahle, etc may have something just as good or better for a more modest price.

According to here https://ls1tech.com/forums/generatio...acts-pics.html the LSA and LS9 ring sets are the same.

According to here http://www.corvetteactioncenter.com/...l#.UmZvChacRWI the LS9 rings are different from and better than the LS3 sets.

Does anyone know the GM part number for the LSA/LS9 ring sets?
