6.0 vs 5.7 exhaust manifold for sts

im currently running headers on my sts kit but im switching back to stock manifolds because they will perform much better. is their any advantage to swap the stockers for a set of 6.0l truck manifolds?

The 6.0's if they are truck manifolds will not fit in an fbody if they are rearward facing

they were coated and ported at a local place here in DFW area

they will only hook up to the stock y, or any y pipe set up that is made for the stock manifolds
