After reading the pissing contest
In the past even in stock motors it has been an over rev and valve float spitting out rockers. Most tuned cars raise the rev limit for some dumb reason. So above the designed Stock redline the valve starts to float the rocker rattles around and spits out.
Over time you could see stress fractures like the pic above cause total failure.
Other rocker failures have seen the pin come loose and fall out but that's only 1 that I have seen.
Most failures have resulted in valve float above stock red line.
THIS engine is as light and loose as possible to make 200base HP
Combined in the failure here is Forced induction... which can cause valve float with pressure pushing against the valve head.
Keeps the valves open, pistons hulk smash valves, crush the rocker back and out of the engine.
I really would like another detailed reason for failure other than this since I have almost $12k in an engine build and like to avoid turning my money into a pile of sh!t because some companies no names mentioned won't release any information.
