The Ardun hemi heads were originally conceived around 1947 to fix a chronic overheating problem in Ford flathead V-8 motors used in trucks (exhaust on flathead Fords ran between the cylinders to exit the block). For the 49 model year, Fomoco began offering trucks with a much larger flathead V-8 which also was used in the 49 Lincolns. So Zora and Yura Arkus-Duntov decided to build and market their heads in England for Ford-powered Allard sports cars. Around 250 sets were cast before the kits basically became outdated by the introduction of OHV V-8's. California hot rodders got hold of some of the kits and reworked them for use as a hot rod motor, by using cut-down Chrysler hemi valves and Lincoln or Olds valve springs, among other things. Never were very many, but they could make lots of power. Underneath, of course, was a flathead Ford bottom end with only three main bearings, which was the real limiting factor on ultimate power. Nowhere near as durable a motor as a Chrysler hemi.
