Solid Cam, Use it or Not

If its a new engine. No. If its a used engine . Yes I looks like it could be polished up. I always say the same thing to my son. His answer always is. For the cost of a cam is it worth taking a chance that it is bent or cracked. The lifters are the expensive parts. Why buy them twice. Looks to me that it has been in an engine for a while from the pictures.
