It wouldn't surprise me if Chevy tried to save a penny or two by changing the "recipe" of the steel or iron that the cams were made from. The vendors only adhered to the provided spec. Short term quality problems were more likely a vendor issue.
I say this from my experience working at a vendor that provided tooling and stampings for the big three. We would order steel that was to the customers spec ("recipe"), and it was checked by QC. It would then rust through in a few years until Japanese competition magically made UAW stuff better (late 80's,early 90's). If there was a vendor QC issue, we worked to get it back to the customer's standard, whatever that may have been.
