Mill Tolerance
 

About 12 years ago, I got a set of 461 heads and a set of 462 heads. I stored them a my Dad's until yesterday, when I went to get them, rust had ate on them some, and they are pitted. Has anyone had this, and had them redone and been fine? I do not want to waste the heads, but do not want to waste money if it will not work for one reason or another.
