Rocker arm recommendations?

The work we did on installing the stud mounted roller rockers on the small block Mopar Indy LAX heads all those many years ago, and paying $20/hr to use another person's mill, allowed me to understand what you were, and are, talking about Mike. Was thinking about that all day yesterday how the ratio changes on the shoe type and not on the roller. Tough to understand that on the roller rocker arm it is the roller center and not the roller contact point on the valve tip that is the rocker length on the valve side.
