Best way to fix this 340 manifold

Is that a through hole? Nickle rod braze it or take it to a wrought iron gate place with a 6 pack of beer. They should be able to weld it with their equipment in about 5 minutes.

Heat it up so its dark red, zip it with the mig, peen it goodand stick it in a bucket of sand for 3 hours to cool slowly.
