2G Exhaust Manifold Cracks

[Peepers]

Guys,
I took off my exhaust manifold today (2G turbo Spyder) and noticed the following cracks.
See pictures:

I was planning on porting this manifold, so the cracks on the “divider” on the inside don’t really worry me too much as I would probably remove/smooth out that “divider”. It’s the one on the top that concerns me. Should I be worried about this?

Thanks
Peepers

I'd start with a new one.

Yea, get a new manifold. Something along the lines of an sbr manifold would be nice.
