I'm building a 327 for my dad's 55 Chevy. I'm using a Comp Cams flat tappet hydraulic cam CS XE284H-10. I took it out of the box and was cleaning it to get it installed and I noticed that the lobes had a rough finish. I put it in my lathe and turned it slow while running a wire brush over the lobes. I used gray ScotchBrite after the brush and the lobes are smooth. I wonder if this has anything to do with the failures. Pictures are before and after. It's hard to tell in the pictures how rough the finish was before cleaning them.
