With my HS they took the same pushrod. And I'm betting RAIVs were just longer because of the longer valve not the pushrod cup and the stamped rocker.

i have HS 1.5 rockers and OF cam on E-heads with no issues.
dave at SD told me the same thing regarding HS 1.65 rockers vs 1.5. i was/am considering going to 1.65 from the current 1.5 & asked what pushrod length i would need, he said for the 1.65 HS rockers, i can use the same length i have for my HS 1.5.
