Isn't it possible for pushrods to be bent...
 

and there be no audible noises? It could still sound normal with bent p-rods? Some said there would be noises, can someone clear this up?

lol Maybe if your hearing sucks, or you don't know what to listen for.

Usually when a pushrod bends, it bends enough to tick, hitting the side of the holes in the heads.

You will know what it sounds like when you bend a pushrod, sounds like a massive exhuast leak that gets louder as your rpms get higher....
