The reason they can be helpful (in my view) is because many of the cars that used them used several different casting numbers over the production period. So if you can identify a car that used a particular casting number, and a 313/318 engine, then it may be possible to identify other casting numbers that will fit.
The fact that you have two different casting numbers that fit your car, demonstrates this.
I have been doing a little research into this and discovered that the part numbers on the Bristol Cars parts list for the 409 may in fact be casting numbers - I had assumed they were internal Bristol part numbers which are usually meaningless outside the company.
The parts list says as follows;
Part No. 2129196 Exhaust Manifold R.T. Type 408/MII (1)
Part No. 2465879 Exhaust Manifold R.T. Type 409 & 410 (1)
Part No. 2268128 Exhaust Manifold L.T. 2206274
The book ULTIMATE AMERICAN V-8 ENGINE DATA BOOK 1949-1974 BY PETER C. SESSLER (2nd Edition) it lists 2268127 as being a left manifold used on Dodge cars (Dart, Polara, Coronet) with 318 Poly engine between 1962 - 1965. That's just 1 digit different from the LT manifold in the Bristol parts list 2268128 .
It also lists 2129194 as the RH manifold for Dodge 318 Poly engines in 1962 (again only one digit different from the Bristol parts list 2129196)
Anne, I wonder if the manifolds fitted to your car are not the originals, and the reason they have broken is because they were not the right ones and didn't quite fit correctly with the rest of the system or the body.
