The drivers side manifold on my ‘66 was cracked when I bought it in ‘05, I had it welded and used a grinder and large fine tooth file to get the face of the welded flange as flat as possible (I was too broke to get it machined at the time!) then used a fine smear of sealer around the port, so far no leaks.
My 2cents worth.
I love those stories. I saw someone in Squarebird Forum used some "Hi-temp Lab Metal" as a sealer.
My guy used a metal gasket which he's warranteed for a year as a matter of everything he did. Looks all business. Too bad the milling didn't work. Too bad he didn't ignore me about how these don't use gaskets, and he just put this gasket on.
Never owned a car in the day that leaked from the exhaust manifold at the exhaust port. Plenty leaked at the outlet where the donut goes because of wear, cracked manifold, or busted studs.
Now the car doesn't sound like the African Queen.
