Bended is not a word. If you bent the pushrods there is a cause and probably a result other than the pushrods. Look for the cause not the result. a Pushrod a little too short would not bend, a pushrod a little long could bend but it would be because something hit such as retainer into guide or seal, which would damage them. The stud also could pull up. I would also be concerned about lobe damage and/or lifter damage. It needs to come apart and inspect everything, experience says push rods don't bend on their own.
There is no way I would put in pushrods and turn it over, you have other damage.
The problem with valve lash is there are different methods and some people use a little from multiple methods. Using the Comp Cams method on their website and rotating the pushrod works the best, wiggling ain't going to do it, prone to errors.
