Aftermarket crankshafts like your Callies crank have journals that are radiused (curved) into the throw. Stock cranks are machined at pretty much a right angle (90 degrees) where the journal meets the throw. Therefore, the stock bearings are not set up for radiused corners and if you used them on an aftermarket crank like yours, the bearings would bind at the radiused corner. Additionally, aftermarket cranks usually are set up by the engine builder with bearings that have a larger inside diameter. Typically, these bearings will have about .001" more oil clearance that the stock set up.
