I was thinking that the rods are long, and since temperature causes a % deformation, any given % change of a long rod is absent from the OHC design. Both have rockers, no difference really there. Maybe the OHC design has less heat deformation (expansion), can be adjusted closer tolerance (0.002" Henner's recommendation on the 172FMM)
