As i stated in your earlier posts it is most likely the timing belt. There was another user that had this happen to them. Changed the push rods and belt, worked great! no permanent damage.
The timing belt MUST be changed every 1000-1500 hours, i'm not sure of which but it must be done or this can happen. Re-set your timing to TDC, replace the belt and install new push rods. ensure you turn the engine over at least 2 revolutions by hand to ensure the timing is in fact correct. You don't need it to be off a few cogs and bend another 8 rods!
Its just one of the joys of engines that run timing belts instead of gears or chains.....
Good luck!

It may be as simple as one rod got out of adjustment and fell out of the rocker arm and the others followed suit after you continued to try and start the engine , seems strange that 8 are bent and it ran last time until you killed it
