I have never have to file the oil rings. They're always right to the specs. If yours overlap, you may have gotten a wrong set, which I have seen that happen.

The formula for sizing the top and bottom compression rings is bore size (in inches) x 0.006", and then add 0.004 for the secondary compression ring gap.

according to Wiseco's website the multiplier for your top ring is .005", for your second ring it's .0055" and the gap is .0015 for your oil rings.
With my CPs I went with CP's recommendation, their multiplier is higher than wiseco's.
