The Stovebolt Site Forums The Shop Area Engine Shop cracked exhaust manifold, repairable or replace?

I removed my intake and exhaust manifold to clean and evaluate and there is a big crack in the exhaust manifold, see pics below. I assume I need to replace it but figured I'd ask if it's repairable, or if it is, whether that's even a good idea. The crack wraps around most of the manifold although I cannot flex it by hand (I didn't try to snap it in case it can still be welded).

If I replace it, should I look for another old part or is there something new I can bolt in its place? The intake looks OK.
