Crower 272 Cams... useable???

the scoop is this, thought i was getting a deal on craigslist, guy seemed pretty cool, used paypal so I should be safe but anyway bought these cams, and got them today and am not sure exactly what to think... looks like there was a spun bearing on one of them and they got a bit hot. What are your guys opinions are they still decent? I was told they only had about 2000miles on them and that they were re-polished, which is not apparent to me.
