You are going to need a good surface on the manifold to seal to. Looks like some corrosion damaged the surface and was repaired with some type of epoxy? If so, you may want to use something stronger like JB weld, build up above surface level, and then file flush. I'd also use some hard setting permatex around the gasket and let set overnight before putting into service as an extra precaution. You could try to have it tig welded but it may become warped with the heat and ruin it rather fit it if the welder isn't highly experienced. I went the welding route once and worked fine but the welder had 40 year experience as a welding instructor and had done a bunch of these before.
