7.4 MPI exhaust manifold bolts, are they SS?

[Mischief Managed]

Are the factory bolts stainless steel? Mine were a little rusty, but not terribly so. If they are not stainless steel, is there a good reason to not use SS bolts on the manifolds?

I have decided to go with stainless steel socket head cap screws (Allen bolts) with lock washers and anti-sieze. I suspect they will likely be much easier to remove in the future.

And they're not as "strong"

I think the question asked was a concern about corrosion.
