Ned, the exhaust manifold uses the brass nuts, and the intake manifold uses
the steel ones. The reason for the brass nuts is that the high heat of the
exhaust manifold induces corrosion of the studs, and if the nuts were steel
they would rust to the studs making them impossible to get off without
breaking the studs.

Subject: Manifold Mounting Nuts
Can someone tell me why two different materials were used for the manifold
mounting nuts? My installation doesn't have the proper number of each
(brass and steel) so I need help finding which goes where.
Thanks,
