There are right and left rockers. In this pic, the push rod seats look like they are both inboard. I believe that they should be outboard. Not sure if BB's are the same, but that's the way they are supposed to be oriented on a SB.So I went to the garage today and manually turned the engine over and brought the valves on the pasture side each set up to The closed position.. after going through the valves on that side, I have at least three lifters that are not pumped up that is I mean when the valve is closed I can push down on the rocker arm not very far. The picture shows the orientation of the rocker arms. I think they are in the proper orientation.
