Bent my first pushrod.

I've been trying to dial in my fist engine rebuild (273 with adjustable rockers) and after setting the lash post break-in I noticed the Cylinder 4 exhaust lifter was really loose. I figured I had accidentally skipped over it during assembly and set it to .014. After trying to tune it today I was getting some noise from the passenger side valve train so I checked it again and it was still way loose so I pulled the pushrod and rolled it on a granite counter top. Sure enough, there was a slight wobble in that rod. I did the same to the other rods on that side and they seem to be straight.

So my questions are; since I spent so much time and $$ on this motor should I just replace all of the pushrods to be safe? Since the rockers are adjustable is there a sweet spot for rod length I should look for since my heads were decked? The current rods are 7.5".

Any advice is greatly appreciated.
