exhaust manifold and orignality

The exhaust manifold on my early 29 is shot and I was told not worth restoring. I'm considering the Bratton's replacement vs. finding an original to restore. How "correct" are the replacements? These are parts 13690 (exhaust) and 13610 (intake). Thanks
 
IIRC, the replacement exhaust manifolds "mimic" the earlier manifold (i.e. they don't have the reinforcing rib described in the Service Bulletins as occurring after 1930 or so) but are reinforced "internally" to achieve the same effect.

So you may be better off in maintaining appearance of originality than a (say) 1930 or beyond fine point restorer.

From what I have heard - both the Bratton's & Snyder's manifold units are excellent modern day reproductions and I am sure will work well for you. If you plan on 'showing' the car in Fine Point Judging, and are really concerned about risking a possible point loss, then you would need to contact Steve Becker at Bert's Antique Auto, outside of Denver (phone: 1 (800) 321-1931. Tell Steve exactly what you need and he will most likely provide you with the correct ORIGINAL set of manifolds, in excellent condition.
Also, it is often times worthwhile to ask either Bratton's or Snyder's if they have a good set of original manifolds - they sometime do.

I concur with Tom. I replaced mine last summer because it was leaking badly and nothing I could do gasket wise would solve the leak. The new once looked identical and worked flawlessly. Once removed, my old one was warped in about three places.
 
FWIW, a reproduction exhaust manifold (mfg. by Snyders) can be modified to pass in fine-point judging without deduction.. Some of the necessary details include changing the 'S' into a number on both sides, adding the Delta mark, modifying the shape in the stud mounting area, etc.
