Yep, you can swap between the truck, vette, gto, f-body, CTS V, etc manifolds, the bolt holes and spacing in the heads are all the same.

Gasgets are different though,make sure you get the ones that match the manifold or you may gets some leaks.

Also the exit point of the manifold is different between the different ones. But, yes the bolt pattern to the Head are all the same and can be swap.

which ones use different gaskets? I just put the 12558573 PN into GMPartsdirect (great for crossreferencing stuff if you have the PN) and it looks like that gasket was used on the 4.8,5.3,5.7,and 6.0 motors in vettes, f-bodies, gto`s, trucks, suv`s. I wonder which gaskets I have, I swapped from truck to f-body manifolds and I have no idea if I ordered gaskets from a truck or f-body when I did that.

EDIT: In order to get the site to give you a list of applications you have to search the PN from inside their catalog section and then click on the description. Just searching the PN on their main page won`t get you the cross-reference.
