anyone ever bent a pushrod and not bent a valve?

my friend has bent pushrods b4 without hurting the valve.

he had bone stock e7 heads and put a triple valve spring on it. the boss for the springs was too high and the innermost spring would bind up and the pushrod would bend.
 
I've taken apart a decent running engine and found all 16 pushrods bent a little bit.

I've also bent a pushrod by having it on the edge of the lifter instead of the center. That bent the pushrod pretty good.

triple springs on a bone stock e7 head? what the heck cam was he using? man i bet that car ran like crap with a cam that would need triple springs in combination with stock e7 heads.
 
dropped a nut

i bent my exhaust valve....dropped a nut in the intake when i was changing my injectors..did not know till i fired up the engine.did not run long..maybe 10 sec then it locked up !
 
My dad did at the track. 351 cleveland, bent 7 pushrods and snapped about 2 inches off the end of one. Didn't bend any valves or mess up any lifters, all he did was pull the old pushrods out and replace them.
