cam/lifter rockwell ?

Should the cam and lifter be the same? No - never. If you want to see two metals eat each other up (cam to lifter, bearing to race, etc) just make them the same hardness. One of the two has to be a little softer.

Keep in mind that abrasive wear is the fastest growing type of wear you will see. Ever have a bearing go out in a rear end? It starts with a low growl, then just keeps getting louder and louder until it sounds like someone is running a bench grinder. That is a good example of abrasive wear. Once it starts, there is no reversing it. It just keeps getting worse and worse.
