You got that backwards, the bolt ripped out of the head then the stand broke!
Once you breaker an exhaust rocker or any part of the exhaust valve train at WOT, something on the intake side is going to break, NOS or boosted is ten times worse. The area of the intake valve is too large and with the left over cylinder pressure from no exhaust stroke, there is too much load trying to open the intake valve so the weakest part of the intake valve train is gonna break! seat,.
