'Ya know.......that casting flaw in the Corvette valve covers is a very interesting story. I've heard that the aluminum foundry mold was broken and repaired. There's a lot of older, ex-Corvette Plant workers here in St. Louis with some neat stories. Anyway, these Corvette valve covers were cast several at a time like a sheet of stamps and it was deemed to expensive to repair the mold instead of making up a brand new very expensive new one.
