So what you're saying is that the rocker jumped off of the pushrod, without the poly lock backing off?

Are you running guide plates, or self aligning rockers? With self aligning rockers, you could have enough flex to allow the rocker to pivot sideways and jump off of the pushrod, you'd be lucky not to un-key a valve.

It sounds as though you have reached the point where you have problems with flex and stability.

Are the pushrods good chrome moly pushrods, with the thick tube wall? For example, 5/16" x 0.100" wall, or 3/8" x 0.125" wall?
