if you're truly "building" the motor, then go with neither.

and get a custom set with higher compression.

you need to bore out .25 if you want the oversize anyways.

imo, i'd go with the os so you get a fresh new hone/and crosshatching. this would increase your chance in achieving piston ring seal with a new snug fit, which is basically means "breaking in" you new bottom end/motor. Then again, im not sure if you are doing a total or partial rebuild. my 2 cents
