As has already been said your pushrods are way to short
I split an INDY Black rocker this way
Non stock parts was the culprit.

Correct me if im wrong, aren't Indy rockers T&D?? Or not any more?
Absolutely. We just saw another member here have the same problem, they also had the adjuster cranked way down...and as (I think it was 'Lewtot') pointed out the adjusters in these rockers nowadays are made longer than they used to be = even less threads should be exposed on the south side of the rocker.This is correct. Some folks think "aw it's just imperfect geometry", but the reality is, you can see the incredible stress you are putting on the rocker with pushrods that much too short. The rocker has no strength with the tip of the adjuster cantilevered that far from it's body.
