So, I have all my push rods in order from where they came out, inside a box, and one my kids got in there and played with them, now they are not in order they came out. I do have them organized still which came from the intake manifold and which came from the exhaust manifold. What kind of problems is this going to cause? And what would I have to replace in order for it to work the best it can? Thanks

 

Although it would have been preferable to have kept them in order, due to the unique way in which each one will wear slightly compared to another. I don't think it will be much of an issue.
The hydraulic lifters will compensate for any minute wear that's been incurred. Especially on a street driven truck.

^^^ True dat!

The biggest issues guys have are putting them in the wrong holes. So after you get them back in and the rocker shafts mounted, rotate the engine by hand and watch EACH rocker compress and release EACH spring.
