I ran into the exact same problem with Comp, the sides of the lobes were nasty looking, as matter of fact there was enough flashing on the sides of the cam lobes on #1 cyl if you slid the cam ever so slightly forward, the intake lobe flashing would barely catch the exhaust lifter and actually lift it. So I pulled the cam and sure enough the side every lobe had some sort of flashing on it, (some worse than others) and this was a spec'd cam not an off the shelf kind of thing. Sent the cam back, 3 weeks later it came back with the sides of the lobes all dressed up like it should've been in the first place. Comp Cams... never again, QC is somewhat questionable in my opinion.
