After you put them back in you should check the alignment of the nozzles.
As you can see in THIS LINK there is a gauge for checking the alignment. You can also see in the picture that the water jet is hitting in the center of a 1"(aprox)square spot on the pan after it goes through the hole in the target gauge. I have for years checked alignment by just making sure the jet hits in the center of that 1" square spot without using the gauge.
