273 taper limit?

Allrite fellow a-body poeple got the charger 273 out & totaly dissassembled saturday. heres where im @, the worst hole is rite @ .005 taper & was wanting real world exp on it if would be smart to over bore or just re re-ring & keep on trucken? id really like to keep the high comp pistons in there cuz that would save me apx 650-700 bucks in correct pistons & machine work. i cannot beleave how good it ran with the top ring gap's @ .078!! & #6 had a small pice of ring broken about 1/4 inch long just goen along for the ride never tutched the cyl wall that i can tell!!! & yes it did use oil mainly cold though. I just dont want a oil drinken pig in 10k again id think .005 would be good to go again but lets hear it. The rings were SHOT for sure so theres the oil consuption fer sure! (sorry spelling isnt my strong suit) now trannys on the otherhand...............
