No one ever talks about the other half of the rocker arm geometry, as if it does not exist. Maybe it's un-important, although there seems to be no shortage of issue/failures on that side.
On the contrary, I talk about it all the time. But, it is the side that the geometry is designed into the rocker itself, which is why the OP is showing the custom B3RE/T&D rockers, so with off the shelf stuff, you correct what you can. The valve side being off will tear stuff up quicker than the pushrod side, so it is the higher priority.
