Hunter-Healey Twin Cam Head Drawings
The drawings below are a faithful reproduction of a series of design drawings by Harold Hunter for a twin overhead cam head to suit the Austin Healey 100 . The drawings depict more than one design for various components of the assembly. Unfortunately I have not had access to any of the completed heads, so I cannot comment on which (if any) of the designs shown here were produced.
