The drivers side manifold on my F broke in a similar way ~20+ years ago (the first time I owned it) and I had it welded by a tech at Paul Russel Automotive in Essex, MA (they do all of Ralph Laurens cars). At some point in the last five years (I’m guessing, based on the appearance of the break surfaces) it broke again but in a different spot which may be even harder to weld. In the attached you can see the first weld (that has held) and where it’s broken now at the forward end of the flange “ear”. I did a temporary accommodation with washers and double gaskets and I’ve yet to remove the manifold as I was waiting for driving season to end (which it has) and will do that this week. A friend here in Maine said he knows of a welder/machinist that has an oven and can superheat the parts so I’ll bring it to him to see if he can do it. If that’s a no-go, Club member Mark Love said he had a similar problem and has a craftsman welder in Calgary that fixed his.
