911 for 411 sb mechanical rockers

All right that's driven me mad and made my day all the same time.
Thank you to everybody that got back to me on this .the little ratings buttons in the threads I need to be able to use more of them likes and agrees and thanks all together.
They're beautiful rocker arms just not what I need. If only the small block stuff look that nice (strong) the Arched rib across the top the gusset coming down from the oil hole to the shaft barrel all top notch .
A couple of posters in this thread have expressed interest and making an exchange of some sort for them . After I speak with the vendor tomorrow sometime I'll get back to those folks in the order in which I contacted them this evening. And I'll asure I'll ask no more and no less than I have into them.
