Installing new cam and want to make sure bearing surfaces are not going to mess it up. My old cam was in otrocious shape. Head was machined and cleaned very well. I installed new cam to measure valve lift etc and noticed that after a few rotations, new cam has marks on its journals (not scratches, just very slight marks). I inspected bearing surfaces and noticed that the aluminum has a few tiny metal specks embedded in them. Probably shavings from the old cam/rocker pads. I'm not sure if they will mess up my new cam and if those marks turn onto groves but I don't want to take any chances. Head cam bearing surfaces don't look too bad otherwise.
Any good way to clean them up? Though about lightly spot sanding them but don't want sand paper particles getting embedded there as well.
