I threw the heads and valve covers on a '69 Ply 440 and a '65 Ply 318 poly. The 440 measured 23" at the widest point on the VC and the poly measured 24.5". The 440 was 17.5" tall from the pan rail/cap bolt to the top of the VC's. The poly was 15" from the main cap bolts to the VC's. I do have pictures. I'll send them to Gary H to be posted if he wishes.
