Looks like an old repair. That spot even has a different surface than the rest of the manifold.

It definitely isn't an old repair....It is raised only on one side and goes right back into the manifold and the symetrical pattern of the metal itself matches all the way around.....It just looks like it blew outward.....If I get a chance I will take some better pics of the area in question
