I read reground cam shafts do not last, but that was so true with flat lifters…are you saying your reground cam shaft have not gotten lost lobes??

If so, are yours coming from one company?? If so perhaps I should consider having my cam reground.

One of the concerns is the re-treatment on the surface.

And rather they can just up the duration and lift just a little bit.
