A motorhead friend of mine up on MI came to the same conclusion about the 
516 and 915 heads.  So one year at the Nats he bought up as many sets of 
516s as he could find (at great prices I might add since they were 
practically being given away as no good), converted them to the bigger 
valves, and sold them at a nice profit.
