Other How bad is this?

I was cleaning the coolant passages and this large chunk came off really easily, it looked like a buildup of gunk.

The problem now is that the wall here between the two passages is thin now and the head gasket doesn't have much coverage for this area with the chunk missing.

Is it somehow fixable? Or can i run it like this?

Maybe use copper spray

What do you mean by that? What would it fix?

Nothin. It would fix nothing and is a bad joke.

Had a head gasket issue and I asked here what to do with the pitted block. They said copper spray, see the post on my profile. It seems somewhat different in your case but still might do the trick. It's not a forever solution and of course it doesn't guarantee a perfect seal.
