Used solid rollers

Thats supposed to read "Solid rollers" ..I got a set but some of the rollers have some slight marks on them. Can I smooth them and use them or will it eat up the cam lobes? The marks look like maybe 2 lifters spun and scuffed the roller and 2 more look like the valve edge dented them. Dents will file smooth leaving a small 2mm wide divot but the scuffs don't look good. Does anyone sell the .750 rollers to rebuild them? I can get the axles out. I think they are solid Crower Hemi with bars. Also looking for some v shaped tie Bars to convert to LA spacing. Look like these
