I am having a ticking noise. I believe its the pushrods. I just ordered some, they are the chromemoly ones. Whenever I install them do I need to adjust anything?? Its it just a swap or is there anything I should do?
This is my first time attempting this and just want to know what else should I do when installing new pushrods. The Rockers are torque down to 22lbs. right?

If so, return the pushrods. Unless you plan on picking up a cam down the road.
Take out the stockers and check them on a flat glass surface. If they are all straight, you have a different issue causing the tick. Assuming a stock valvetrain, if you have a bent one, replace it with a stock straight pushrod.
The problem with running a hardened pushrod on the stock valvetrain is that the stockers will give on a mechanical over-rev saving the valves from hitting the pistons. Hardened pushrods will put your valve into the piston on the over-rev.
