Goodhart, I'm not trying to diss the product you sold me. I just don't know enough to know if I should be concerned about this.
Look at the main journals on the cam, they are a bit scored, enough so that I can just barely feel it with my fingernail.
Are these okay to run? I suspect its not a big deal but I dont want to have to rip these out again, or damage my rebuilt head.
*note: the little stringy things are just threads from the rag I was holding it with, not metal shavings or anything.
