Bent Pushrod?
Bent Pushrod? what are the common symptoms?im thinking that you wont notice a big performance loss,since its probably only one.when im driving,also at idle,when i rev it a little hard or just give it a good amount of throttle;i get this ticking noise from the drivers side engine compartment.no power loss.im going to check all of my manifold bolts;since i just put them back on a couple of months ago(got busted w/LT's).im pretty damn sure it isnt an exhaust leak(i just got tit fixed,not too long ago.when im under the hood and i rev it,it sounds like its in the head.how easy is it to bend a stock pushrod?its a LOT louder when its cold.TIA.any help will be greatly appreciated. 
It could just be piston slap... Did you over-rev the engine. You will not bend any pushrods unless you do so. You can check the pushrods, it should take about 2 hours to check them all. Just roll them on a table and look for imperfections.
i didnt over-rev it.i talked to my pops and he said if i bent a pushrod,i would see a misfire or a stutter in performance;which i dont see.since i last worked on the exhaust,i think it is the culprit.im going to check it out when im finishing the install of my F2 TNT kit. 
ill keep you guys updated on what happens.thanks.

I bent two of them and my car ran great
Sounded like a possessed clock though 
Does the ticking get louder or speed up as the RPMs increase?

You won't really notice a performance loss with a couple bent ones, but you will notice a miss once and a while. It's very slight usually. I had two bent ones, but the car ran great. I even took it to the track during that time.

I am in the middle of my cam swap and I had a bent pushrod. The car made a loud ticking noise but it did not seem to hurt performance. Hopefully the hardened pushrods will prevent any more bent rods and the ticking goes away!
Funny to see the differences between people's issues.....
I bent 2 push rods on my '99 Z28, really didn't notice a power loss (just felt "flat" up top), that is until I ran another LS1. Less mods and it walked away at the top end of 2nd and into 3rd (and I'm not a rookie when it comes to racing).
I did a dyno to see if I could find out what the issue was, keep in mind I didn't know they were bent yet, and the car only made 286 RWHP with a LM and lid and the graph was rather "bumpy" not smooth.....but no knock beyond the normal LS1 knock.
I thought that was a little low so I spoke to the shop owner (Very good LS1 mechanic). The shop owner looked and stated that he thought it was bent rods. Took the car home, took it apart and found 2 bent rods. Upon replacing them, I took the car back to dyno again, felt stronger on the top end. With all the variables being set as close as humanly possible (I'm ****) the car made 324 RWHP with no other changes . Take it for what it's worth; I just saw these other posts and wanted to give you my 1st hand experience.
Best of luck ! !

I put some "Hi Tech" comp pushrods in my car about 1 month ago and my car still sounds like it has a VERY loud valvetrain. Im going to go back and take them all out just to make sure.

Well I finished all the bolt ons and tuned it today ran great but it has been about 4 months since I drove the car I miss shifted reason one rusty on driving, reason well excuse 2 my shifter is shot, I just think the 122000 mile stock pushrods just couldn't take it anymore, a ms3 cam kit is getting poped in but it will miss fire very bad check engine light flashing,and almost stallin,but I think I have about 3
