Hope I'm not over stepping here. I am not a engine rebuilder, but have installed cams before. I do not want to repeat what was already stated. I do hope cam lube was applied to the lobs while install, do to all the dry runs, before proper cam break-in. Never had this issue, but I would think a Dial gauge reading at the rocker arms would let you know if the cam was in defect, before taking down the install again. Just saying!!!
