You're not propagating bad advice Tom. Cast iron isn't easy to weld. An exhaust manifold doesn't have a lot of stress on it, so Garry's method will work, especially if you have the manifold somewhere it can cool slowly (the slower the better!). After "stick" welding (with a special high nickel rod made for cast iron) it would be a good idea to heat it back up with a torch then let it cool slowly. 

Most castings, especially if under stress once installed, can't be so easily welded. Brazing with a bronze or brass rod would work better/easier, but be more noticeable unless painted, and we all know paint doesn't stay long on an exhaust manifold. But then the exhaust manifold is not real noticeable on a 196, being partially under the intake area of the head. Maybe some of the Eastwood exhaust manifold coatings would work well though, haven't tried any.

Really? I always thought that cast manifold stuff was unweldable!

Sorry for propagating bad advice then.
