Proper hone and ring selection and the rings should break in almost instantly. Moly rings in a cylinder that's been torque plate and plateau honed will break in immediately, during the engine run-in.

Once the initial run-in is done (cam break-in if you have a flat-tappet) take the car out and drive it like you stole it. if the rings aren't seating it's probably that the wrong finish was put in the cylinders for the type of rings used. Moly rings like a real smooth finish. Old school iron rings need a more aggressive crosshatch.
