Every motor I have built HS 1.5 and 1.65 take the same length pushrod.
As far as rocker length-yes the BBC is longer from the stud to roller tip. Ratio changes are on the pushrod cup size distance as the trunnion/stud to valve distance never changes. f you want to see something crazy look at ahigh ratio SBC! pushrod way up there on a really short body
