yeah... teh ones UNDER the manifold and UNDER the exhaust are teh same. the only ones LARGER are teh ones ABOUVE that you can see ONTOP of the manifold. and they are bolts not studs. just those 3 are different. trust me on this one, ive been back and forth on the intake/exhaust studs many a times.

Generally, only "round" and "square" ports, including the heads with emissions liners, are referenced when discussing exhaust ports on the L6 heads.
