Adrun heads were designed by Zora Arkus-Duntov and his brother Yura. Their design allowed hot rodders to convert their stock V8 Ford Flat Head to a overhead valve configuration featuring hemispherical combustion chambers.  These heads were first offered in 1947 and are extremely rare today.  The Belmont Super Service Roadster motor below is fitted with a pair of original Ardun heads.  For extra performance this 32 hot rod is also fitted with a GMC blower running 8 psi.
