exhaust manifold nuts
Is there any reason why I shouldn't use stainless steel nuts to secure a stainless steel exhaust manifold to the cylinder head of a Pinto?
Are brass nuts normally used?
Cheers
Nick

Brass nuts are the norm. I don't know why, it possibly has something to do with rusting and siezing, but i used stainless nuts on my A-Series
and it was nothing a large hammer wouldnt remove.

I don't understand why people (and car manufactuers as a matter of fact) still bother with normal bright steel nuts on the exhaust manifold.
They allways cause problems when it comes to getting them off. In my opinion stainless nuts are the way to go!

Cost, no galvanic reaction from using dissimilar metals and realistically, what are the chances of the manifold being actually removed from the head?
For every engine that is recycled and needs the manifold removing there are probably 50 times as many that will not ever have the manifold removed in
its lifecycle.

Honda use stainless nuts on the head to manifold join but don't use stainless studs.
