Aging aulminum heads

[russcc]

Thank you all for your suggestions. Right on, Barney would expect I would run them, not hang them on the wall. If I could have found an original set of Navarro's, I would have bought them. No luck, but I got a chance to meet Barney in person, and tour Navarro Engineering. The 700 HP turbocharged Indy motor was cool. Barney was always light years ahead of the times. The Easy Off is a great idea, and simple. Thanks again.
