SB Rocker Arm Geometry

Fishy I saw an old post of yours describing the same problem you had with the comp rockers. One possible solution, if I want to perfect the scrub pattern, is to have the rocker shaft stands milled slightly (.030" - .060") and that would move the scrub pattern back toward the shaft allowing it to be centered on the valve stem. I do think I could run it as is because the roller tip won't put a side load on the guides like you say. A centered scrub pattern is more critical on non-roller tip rocker arms.

I'll keep looking into it because if I can get it corrected via milling of the stands I might go that route. That will require a shop that really knows what they are doing not to mention one I can trust with my Stage 2 ported heads and expensive rocker arms.
