Good practice is to "dress" the backside of the castellated nut if necessary against some very fine abrasive cloth backed on a flat surface to get an alignment of the cotter pin at the correct torque. Of course clean scrupulously before assembling.

I'm not familiar with your specific engine. If your rods just have plain castellated nuts, then the bolts will have been drilled and you must use cotters or wire. If the bolts aren't drilled for cotters then one of the many types of self-locking fastener was used.
