Exhaust Valve Cooling Nozzles. Copper nozzles installed in the cylinder head in such a manner that the opening near the upper end directs the flow of water toward the valve seat.
I have never heard of these, or seen them. I wonder where they were used. :confused:

They should have been old news by 1954 though. This page has a picture and description from the shop manual: http://chevy.tocmp.com/1948_51truckshop/51ctsm0604.htm Curt B.

Thanks for the info. The workings of the heat riser valve shown on that same page were pretty interesting too.
