Herewith is E.CD.536 which shews a modification to the overall height of the cylinder head to avoid the cooling strains in the walls of the rocker compartment, which were a source of anxiety to the Foundry, in the original design. There is a slight modification to the angle of the sparking plug. The head should be detailed to this E.CD. drawing. DA.{Bernard Day - Chassis Design} SWDL{Len H. Swindell} | ||
