Similarly, the "Pan-Head" Harley had valve covers over it's in-head valves, that looked like cake baking pans, thus the name "Pan-Head"

This model engine is a "Panhead" Harley engine. They were produced from the 1950's into the 1960's. It has that name because the head covers look like baking pans. The "Knucklehead" engines looked very much like they were taken off of a radial aircraft engine. The valve rockerbox bolts are exposed on the outside of the valve cover.
