some 9" decks had 2.250 mains (small ford) and 60 mm cam journals.
something noticable the cam is bigger than the crank.
also some were made with 47 degree lifter angle.
9" deck is cross drilled between siamised cylinders for additional cooling.
I would think they all are suitable for procharging, regardless of deck height.
depends on cost, tall deck hard to find?
