Anyone use speed master roller rockers?
The reason the PRW/SM SBM rockers have a spring clearance issue is because they patterned them after the Comp BB rocker body design instead of their SB design.
On an ootb SM Aluminum Head the PRW rockers had hard contact with the retainer, and the roller was way up off the valve tip.
A Crane Gold and the Comp rocker both had tons of clearance.
