Bent push rods

Hello Everyone

I recently had a LB7 engine given to me, the truck had apparently up and quit going through an intersection. It was believed that the camshaft had broke.
I am in the process of getting the engine stripped down to see if it will be worth rebuilding and then installing in something.
I have the heads off now and have 1 bent pushrod on cyl. 2,4 and 7 (not sure whether intake or exhaust). All 4 valves on cyl. 2 have contacted the piston, 2 valves on cyl. 4 and 7 have contacted.
The cam does not seem to be broken, but I don't have it out yet, anyone have any thoughts on what has occured.

Thanks for the reply, I was thinking along those lines, float the valves and they tap dance on the pistons.
