I've installed two or three repro exhaust manifolds and have had no problems with gland rings.
All the old original manifolds I have, including a late 31 with the extra web have drooped and won't work with gland rings. When you install a repro manifold, leave the two bolts that attach the intake manifold loose while you tighten the four big stud nuts holding the manifolds to the engine block. Then snug them up last. No more exhaust leaks.
