Any part numbers or markings? I had DR regrind mine, and the ends came back stamped "SC" where before they were "930"

Are the ones you bought reground from another profile? IIRC, when the cams are reground, they have to reduce the size of the base circle, so while the lobes may look shorter, the relative lift between the base circle and top of the lobe is actually greater.
