Custom piston is a custom piston, contact a piston manufacture and be apt enough to talk with an engineer, and there you go. Depending on dimensions that want to be carried over from any other given piston (ring assortment, fit, bore, pin size, skirt characteristic) an example should be sent to the manufacture. That would be the method for a flat top or a dish piston anyways.
The 171mm of the carrillo rod is rounded, you get proper documentation on the length but as with anything, final fit is up to machinist discretion.
Personally, at that length in the 2.4l block, I would kick the piston pin size down to 19 or 20mm to better suit the piston height, you will be doing some intruding onto your oil rings.
These rods were designed for NA race use btw, good rod, still a lot in use today, they have been around a long time.
