All the Mopar Poly heads where made for economy, cheaper to make than the Hemi heads in 1954, two barrel intakes, geared for the old people who bought the cheaper Chryslers, Desotos ,Dodges and Plymouth. they where not made to make good HP
I do know that Plymouth put dual quads on there motors for several years in the mid to late 1950s before they switch to the B and RB motors.Dodge got it correct using the Chrysler 354 dual quad Hemi motors in there D500 cars in 1958 More power to those that want to turn a non HP motor into a powerhouse Good luck
