Quality of the Rockers might not be good, who knows, but checking spring pressure is an excellent idea. Bouncing them is no good.

Maybe rockers, but first place to look is springs,if you break valvetrain most of the time you will find springs are too weak, from worn out and lost pressure or just too weak to start with and has beat on rockers long enough they have started breaking.
