Advice needed on manifold repair

There's no distortion on the intake port crack, or other shift that would require machining. I'm thinking about about what CH 1 II said about brazing it. I had good luck with that before. I have practically nothing in it.
I was thinking the same brass brazing rod low heat then file and shape etc. But is it worth it? Depends on how rare I suppose and orange paint would cover the repair. Ih ave an old square bore intake I have to check out with similar issues not cracks but bolt hole issues.
