Possibly cheaper.

I have a whole bunch of these that have started pitting or showing some kind of wear. Not bad, but needing to be refaced. Some to be rebushed first. I don't see these as throw away items.

I may have this all wrong, but I got it in my head that neither the cam lobes nor the rocker faces are hardened to start with. But that as they wear against each other they harden each other, at least, literally, superficially. And part of the drill of breaking in new cams/rockers. That's the hadening that pits and such have gotten through.

So why not start off hard. Of course, there may be a very good reason not to do this. If so, someone will point this out.
