Those cams have been in a bike! You can clearly see the path the roller from the lifter left on the lobe. I would be asking for a refund my friend. TMTCW.
I just changed out my stock 2003 UC cams for Andrews 26a cams and my stock cams had wide spots in the cams as shown in your 3rd photo. Andrews cams have the same width all the way around the lobes, at least on the cams I installed.
