difference in exhaust manifolds?

Did GM ever have different style passenger side exhaust manifolds? One with a donut seal and spinning flange on y vs's flate flange no dunut seal and welded flange on the y pipe? Keep in mind this only pertains to the passenger side exhaust manifold.

Manifolds are different between 4.8/5.3 and 6.0. Don't know of any other changes.
