Check your cam bearings,,also,,before you go running that motor,,,flush the crap out of it,,,and take the pan off.
You said the cam lobe was worn down??? the metal went somewhere,,,,,Measure every thing three times,,,and install once.
P.S. replace all lifters along with the new cam.

All the other lifters and lobes look like new.
