I've heard you can straighten them, by using an air chisel. You rest the cam in v-blocks on the end journals, turn the high side up, and with an air modulated air chisel and a dull bit you can hammer next to the center journal. You and I would have to sneak up on it, but I'm sure the guys who do it all the time could do it in a fraction of the time it would take a rookie to do. Of course, its a casting so it could break, too, even if youre careful. Comp cam could probably fix the cam you returned.
