Default Jumped Timing Bend Pushrod?

Had a previous post about some loud ticking noise after I changed my timing chain. Pulled off valve cover on noisey side and found #8 intake had a bent pushrod.

I'm assuming it happened when I jumped timing. I did not think that the piston would hit the valve when timing chain jumped. In any case I removed rocker and pushrod on exhaust also and ran air into #8 - no air thru carb (or exhaust). Was able to push down on sprng so valve doesn't seem stuck.

Anything else I should check. Will be installing new pushrod when it comes in tomorrow.

I'd check the rocker to make sure it's not bent or cracked. I've seen that before, believe it or not. Other than that, I think you should be good to go.

Good thing your pushrod bent and not a valve.
