Harlon sharp roller rockers

The bent pushrod was the next one over when the piece got stuck under it. No bent valves.Checked coil bind this morning when I checked the spring pressure. The springs were new this spring an havent got over 25 passes on them. I always back them off between races to since our races are 3 weeks apart. Never seen these do this before is why I am so baffled. Could it just be fatige from 6500rpm for 60 seconds? Looks like about 2 threads on the bottom side
