shot peening a distributor gear for a roller camshaft

Apparently Chrysler didn't use billet camshafts for their roller blocks.
If it's a billet cam then we need to use a melonized gear

Is your cam a Billet solid roller?
Or is it a hydraulic roller?
Sorry if I missed that if it was mentioned.
Most or maybe all street hydraulic rollers are just a cast core, that usually any cast distributor gear will work.
Billet steel cam usually requires a bronze distributor gear.
At least that's what I've seen...
