Default Exhaust Manifolds

Are the 5.7L LS1 exhaust manifolds the exact same as the 5.3L exhaust manifolds. Basically could you take a 5.3L exhaust manifold and bolt it onto an F-body car and they line up with the f-body's stock exhaust?

I don't think they will fit considering the aftermarket headers aren't interchangeable.
