Brass nuts on the manifold head pipes minimizes the possibility that the head pipe nut (s) will come loose. The brass nuts expand/contract at a different rate than steel, therefore they are more stable. Regular brass exhaust nuts are thicker than steel, by approximately 1/8", therefore they get a better purchase on the stud.  13mm hex
Good brass exhaust nuts are very hard to find.

It is OK to use Steel washers with the Brass Manifold Nuts
