Inliner Pat Swanson, whose loving replication of the 12-port Chevy Spalding roadster is featured in the current *Rod & Custom*, is the acknowledged expert on the evolution of 12-port heads. i think we can say that this head in the Iacono/Ganahl dragster is a GMC "Wayne" head designed and manufactured by Harry Warner in the later 1950s. Mr Warner then owned the "Wayne Manufacturing Company" and the rights to the name.
Under the "Historical" link on the Inliners home page we have a series of articles by Herbert Hall on the Wayne Horning and Wayne (Harry Warner) 12-port heads. In the third entry in that series we can see Mr Hall's explication of the supposed "advantages" of Mr Warner's design. Those heads have run fairly well, in the right hands. It occurs to me that they give new meaning to the term "flathead."
God's Peace to you.
