On the LS6 manifold, it has a flatter bottom and 1 verticle w 2 horizontal ribs in the area between the ports.
Note the difference in the area between the ports and the LS1 having the bump in the middle.
The STOCK LS6's also do not have EGR provisions, unless the are fabricted.
Here is a pic. The LS1 is on the left.
