Mr. Gasket Rocker Arm Stud Issues

What brand of rockers are those? Mainly, Any course of action on your part is going to require educating yourself on multiple aspects of the valvetrain or enlisting someone who knows Mopar valvetrains and what geometry is. Just going by your picture it looks like the adjuster “ball” is too far from the rocker arm body flat. Like YR mentioned, that means your pushrods are too short. The rocker with the damage looks to still be usable so replacing the adjusters as a set would be my first course of action. With which ones? And what else to do? Gonna take some research and education or the enlisting of someone knowledgeable to correct everything.
