There's a quite detailed paper on valve cooling here:

There's a few other interesting bits and pieces here under the heading The Piston Engine Revolution:

   Very interesting read.

   I was about 8 years old when my Dad bought a 1947 White truck with a Hall-Scott engine that had sodium filled exhaust valves. I knew what an exhaust valve was and I knew what salt was ,but nobody could explain the reasoning to me. They just said the valves last longer.

   I was in high school before my shop teacher ( a WWII B-17 pilot ) explained the sodium cycles and cooling effect to me in a way I could understand.

Read them all, interesting, some I had knowledge of.

Once again, my knowledge of engine development has now been expanded.  This paper and the seminar about high octane fuel development for WWII aircraft that I attended at the WAAAM Museum in Hood Rv. OR validates how these developments were critical components in winning the war. 

John, thank you for posting this!
