Again, curious. I always thought that cams were surface hardened which presents the rocker with a very thin, very hard surface that wears slowly. Once you get past the hardened layer then it goes more quickly.

I had a Honda where they replaced the cam under warranty as the lobes were improperly hardened and suffered premature wear. While the dealer did not keep my cam, he showed me one that allegedly had worn due to the same problem and you could see that there was a valley worn in the cam. I say allegedly as I was suspicious of the dealer and asked a lot of questions and demanded follow up....which I got most of.

Also in Wayne's book there is a photo of a newly reground/hardened camshaft.....it does LOOK different!
