See Bob's post earlier in this thread:

The word "gland" used in engineering means a sleeve or box that forms a seal to keep some kind of fluid or gas from leaking in or out. In this case, gland rings fit into a counterbore machined into the joint between the block and the manifold. They reinforce the manifold gasket so that exhaust gases have a harder time penetrating it.
