How much damage on a roller cam makes it unusable

So a NHRA stocker buddy of mine came over and gives me a free roller cam for my Big Block that he says had some damage on 2 lobes. One looked not so bad and the other had little indentations like 3 or 4 from a roller lifter that came apart. I polished the first lobe and it looks good so I did the best on the other and the thing does not look real bad but I am not sure about it. I was thinking that the pressure on the cam from the new lifters would kind of hurt it much but since I have never run into this I am not sure and I do not want to ruin anything. The other alternative is to regrind it. I sure do like the specs on this one though.
