that sounds like a wayne head 'cept they were a crossflow 12 port head. And that was their era. Leo Santucci's chevy six cylinder hopup book mentions something similar to that race and a third place pikes peak hill climb special of the early fifties. I have been trying to find something about the hill climb car on the internet but to no avail.
Wayne heads were to the chevy sixes as the Ardun head was to the flathead ford. Interesting to see how close the two motors turned in track times. For the wayne head on the chevy- check out the internet for "Wayne head"; "Wayne-Horning head" some were made for the GMCs too. Some were cast iron, but most were aluminum. Usually with nitro fuel they would produce over one horse per cubic inch. The onset of the 265 V8 chevy motor killed all interest in the hot six head. so they just went away. In the early 2000s someone bought the Wayne head dwgs, molds, etc and reproduced a few, they were all snatched up quickly, even a registry is being developed trying to locate the existing originals as well as the recently reproduced heads.
You did know that the Ardun head (ARkusDUNtov)was designed/mfg'd by the same Zora Arkus-Duntov of small block chevy & corvette fame? It took chevy boys to really make the fords run. Ol' Louis Chevrolet designed/produced the Frontieac (sic) OHV head for Model T motors in the twenties (commonly known as "Fronty" heads).
A lot of the wayne heads were run on oval track cars, and most are still found racing at Bonneville.
I seriously doubt if any were run with babbited rods, as the popular setup on high output early chevys was to run GMC rods and full pressure oil pumps.
