PN 12560894 also appears to be a LS1 intake.

Re: LS6 manifold? casting #?

Those are BOTH LS1 manifolds.
Not only is the bottom not flat, but they have the X shaped bracing between the ports. An LS6 manifold has a flatter bottom and 1 verticle w 2 horizontal ribs in the area between the ports.
Here is a pic. The LS1 is on the left.

Note the difference in the area between the ports and the LS1 having the bump in the middle.

Ahhhh Thanks alot guys. Its good to have this all cleared up, Bayer, you might want to add a section to the sticky about LS1 vs LS6 intakes lol. I've seen this issue many times and its difficult. If we can all get it sorted out you should add it in.
