I had the left side exhaust manifold on my 300F repaired by Paul Russell's shop in Essex, MA in the late 1990's. Note: He's the guy who does all Ralph Lauren's cars. Now, before you fallâ?? over scared by pricing, I have to tell you he was very reasonable (I don't recall what the price was, unfortunately, but it was very palatable.)
As you can imagine, his guys deal with big issues with super-high dollar cars all the time. He gave me a tour of his facilty and Lauren's Concours winning Bugatti 57C was in his small lobbyâ??, as he stores some of Ralph's cars as well. Needless to say, I was pretty much awestruck.
Anyway, worth considering and a call to them.

When I lived in LA, there was a place in Chatsworth which specialized in repairing cast iron parts (heads, manifolds) by oven brazing them.
In other words, they raise the temperature of the entire part high enough to allow the brazing material to fuse and then broughtthe temp down slowly to avoid warpage, This sounds right to me intuitively.

I got a phone call from a gentleman with a 300G that has a cracked right side exhaust manifold. Knowing how hard it is to find a replacement, can anyone suggest a facility that knows how to repair manifolds? I realize it is a very specialized job that is outside of the abilities of most welders, but may be possible.
Has anybody found someone that knows how to do the job so it holds up over time? If it is even possible? I'd like to help him out if I can, and if you happen to have a replacement manifold you'd like to part with, let me know.
