Having read your post, I suppose that's true re the factory mfg cams.

But that's not the case with the solid rollers initially made from billet...they called for the bronze gears (again, being the cheaper and easier to replace element). Even now, by using an iron gear, I would want it to wear out before the flat tappet cam gear does.

Matching hardness or softer distributor gear is ok...not harder.
