Default Early 1928 Exhaust Manifold Assembly

I plan on using the Early 1928 Exhaust Manifold Gasket Assembly.

My questions to you who are in the know and have experience about this assembly are the following:

What are the Pros and Cons with this set up?

Who sells the best Gland Rings that will work without falling out? I know there are some "gyp" parts out there.

What is the correct size of the gaskets to use? I see that Brattons and Berts do not carry them BUT Restoration Supply Company in Escondido, CA does.

Thanks.

Pluck

my only experience with Gland Rings was some years ago and what I learned was if the surfaces for the rings in the block and the ring surfaces in the exhaust manifold are not perfectly flat and clean, you will crack the ear of the exhaust manifold pretty easily.
The advice given at the time was eliminate the gland rings and you will eliminate the problem.
I obtained another manifold, used the commonly available gasket and am still going strong after 30 years.

Is the early 28 different than later years, as far as gland rings?
For my car (a late 31), I purchased a length of
https://www.aceraceparts.com/collect...ess-2-0-length
and just cut to length (using a lathe). The O.D. is a nice fit in the counterbore and the I.D. is the same as the port.
If the glands are the same (early vs latter) then any gasket would have to have a minimum I.D. of 1.5", at least on the exhaust ports. I have a length of this 321 stainless tubing. If you want I'll slice you off 4 rings, pm me.

TOTALLY different "gland ring" as each individual copper gasket has the gland ring built into it. To my knowledge, no one is commercially manufacturing them presently.

The Early 1928 Exhaust Manifold Gaskets were single rings (not the gland rings). They were copper & asbestos as shown in post #6. I had a set that I got from Doc Kalinka in the early 80s, I have since had no need of them and think I sold them (I think here on FB). At one time I had pictures of them, if I can find the pictures I will post them.

I never knew there was a different manifold, and I have a March 28 car. When my engine was rebuilt I took them out. I did use the copper manifold gasket though.

On a Model T, the rings are used to keep the exhaust manifold from warping. Without the rings the manifold would warp over time so that the holes in the block did not match up with the holes in the exhaust manifold. Cast iron grows slightly when heated and does not shrink back down when it returns to room temperature. Each time it is heated it grows a little more.
