Exhaust manifold crack

I found a small crack on the top of my stock manifold. After pulling it off in order to install my ATS, this is what I found on the bottom. Maybe you should check yours...

Mine was the exact same way, although the crack up top was closer to the flange than yours was. I was shocked to see it all the way around like that.

pretty common w/ 24v manifolds... a large part of why the ATS came out... in fact, the 12v ATS manifolds start out as 24v's and are then somewhat poorly machined at the head flanges
