Bent a push rod - Need advice

[Humbucker]

Darn it! A friend and I just installed new AFR 185 heads. I upgraded to new roller rockers, stud mounted, and hardened push rods. Engine is a 392 Ford Crate.

We got her fired up today, but she didn't run right from the get go. She stuttered and coughed a bit, and bucked going down the road even at 3000 rpm. He felt something was wrong with the fuel setup, but I suspected something bigger.

We pulled the plugs and noticed all indicated a very rich setting except for the #6. It looked fine. We pulled the valve covers and checked the feel on the pushrods as I cranked the engine around. The #6 intake was very tight. We removed the rocker and sure enough, the pushrod was bent. All the other rods were pulled and they look fine.

Any ideas on what might have caused this and what possible damage could have resulted? I fear what we might find... I'm assuming we tightened the rocker too much during the setup. Perhaps no oil was in the plunger when we set this one?

Any help would be MUCH appreciated.
