W2's

Has anyone ever seen pics of the heads that Bob Glidden ran on his Arrow ? I remember he set a record the very first time he had the new car out ! Bob Glidden had to be one of the very best as he did almost everything himself with his family. I would really like to see what castings he used and what was done to them. I know there's his 351 Cleveland stuff still around to see, wonder what happened to the 340/W-2 stuff ?
