There should be two lengths. One size for intake and other size for exhaust. Six of each size. Exhaust are longer. Here is picture, exhaust are one and intake are two.

When assembling an engine the parts have to go back to there original place in order from where they came. The valve adjustment has a great deal of lash that is due to the use of hydraulic lifters. This is made up for by using different length push rods.
I have attached the valve adjustment directions from a service manual.
You will have to move the push rods around until you get them to have the same general amount of lash. This has to be within the amount of lash that the adjusters can handle.

Let me know if you have any questions.

The intake valves use the short ones and the exhaust valves use the longer ones as they are farther away from the cam/lifters

I have 97 chevy malibu 3.1L V6 engine. I have done a rebuild on the engine I was informed that the pushrods might not be in thier correct position. The manual that have says nothing on the correct positioning of these rods. Is there anyone that can tell me exactly how I go about placing those in the correct position? Please make it girl proof lol

OK, there are 2 different length pushrods. If you look at the cyl head there are 3 valves closer to the center of the engine and 3 closer to the exhaust manifold. Long pushrods go to the farthest away from the center of the engine. Short to the closest, almost like a big-block chevy "semi-hemi"

Thank you I think that we put them in wrong I think that we put them in a long one and a short one switching off every hole. So a long one then a short one and so on. So by your explaination I believe that we totally put them in wrong, thanks again and I will let you know what the outcome is.

Ok so we checked the push rods and that wasn't the cause of the engine not starting so what is next. I know there is spark. I checked that already and the gas is fine. What next. The computer had a code that sad p1406 I haven't been able to find that code anywhere. Does that mean anything?

Be sure everything is plugged into the coil pack. There are I believe 3 connectors. One of them comes from near the top of the trans, that might be the one you missed. Hopefully
