Can we have a pic of the bottom of the rocker?

Who makes the rockers?

The stud broke because the rocker has been striking it on the backstroke.

To me, it looks like the pushrods are too short, but it seems you have not enough posilock thread engagement on the rocker stud.

So the only other thing left is the rockers aren't capable of over .500 valve lift.

Shorter pushrods is not the answer.

You do have many issues with your valvetrain, I'd be onto your supplier for a remedy and some
answers.

200 miles, carb too rich.
