SB Rocker Arm Geometry

I had the same pattern when I had some Comp Cams rockers but mine were even worse than yours. Mine nearly rolled off the stem. Yours isn't perfect but it's not terrible either. Since their rollers they won't apply any side load to the valves like they would if they were non rollers. The roller tip is actually too low so the only way I know to correct it is to either run longer valves or you could cheat and run lash caps. Of course if your retainers aren't designed for lash caps they'd have to be changed also. Money-money-money. I tried a set of stock rockers on my heads and they lined up perfectly unlike the Comp Cams so I'm not sure what the deal is with CC but it appears they are made a little too long. But like I said yours aren't too far off to worry about it but that's JMHO.
