No. With hydraulic lifters there's quite a bit of leeway. The cam lobes would need to be much worse to make that kind of noise. Camshafts are case hardened, meaning the hardening only penetrates down into the metal a few thousandths of an inch. Typically it takes years and many hundred thousand miles to wear through the hardened surface, but once that happens, the lobe(s) will go flat amazingly fast (like in ~ 50 miles). Since yours all measure so close, I would think the cam is fine.

About the only thing left is to check (if you haven't already) is play/looseness between the rockers and the push rods. In that video it sure sounds like valve train noise........but hard to zero in on it from a video. Tim
