Why do I keep breaking rocker arms?

What pushrods are those? The pushrod cups look suspiciously large like they would hit the rocker arm at full lift.

Yeah, they look big, & not adjusted, i.e. the ball looks offset in the cup a bunch on the closest one...lots of unanswered mysteries yet..and I posed that question in My 1st post. OP needs real help, not sure He's getting it, at all...
