If the rockers hit the retainers, they're tilting the retainers and trying to un-key the valve every time the engine spins over 4 times. You're lucky that you haven't done even more damage. That is most certainly the problem.

Most modern rockers for a big block will clear a 1.650" spring and retainer with relative ease, provided the valvetrain geometry is correct.
