In 1957 the priority was an engine that was economical to produce and expandable to larger displacements in the future. The heads did get a performance redesign in 1964, and the 426 Hemi was born.
OK but the wedge engines continued on with multiple updates throughout the '60s including head redesigns (516, 915, 906, 346 etc.) for bigger valves... would it have been that hard to tweak the design of the heads a bit to move the valves toward the center of the bore?
Another question how much of an effect does it actually have, as in would the gains be only worthwhile in a racing engine or would it work on a street engine too?
