LQ9 and LS2 pistons are the same? Same compression? Can be interchanged? Have a LQ4 and would like to increase CR.

Yes. Keep in mind LS2/LQ9 pistons came with 3 different ring packs depending on when they were made.

Also, the ls2 and Lq9 pistons have floating pins. Some Lq4's had them too but if you have pressed pins you will need to have your stock rods bushed to run the floating pins on the ls2 pistons.

Or just find set of bushed rods. Prolly be in for the same amount and better design rods.

Sorry for my ignorance but what is bushed rods? I just have the 6.0L block. It came as a LQ4 but don't have the pistons anymore so I'm interested in LQ9's pistons, which increase the compression, but then I would like if someone offers me a set of pistons from a LS2, if are the same? Rods are the same too?
