I've got to ask, why "of course"? Past posts have discussed factory
manifold vs aftermarket headers, and my recollection is that if you
have the correct factory manifold, in good shape without any cracks,
you're usually better off using it rather than an aftermarket header.
Nissan actually did a splendid design job on most of the bits on these
cars, and reportedly their manifold is a better match than aftermarket
attempts.
Good manifolds are also rare and expensive, so a good header is
a good substitute if you don't have a manifold available. (key word
being good, there's also lots of past discussion on flange width,
proper washer spacing, etc etc). But it's still a substitute.
As far as heat and the starter, yes that's a concern. And wrapping
the header can lead to early header failure (traps too much heat).
Jet-Hot ceramic coatings help a lot, I understand, but I have no
personal experience. A gear reduction shorty H20 starter is a great
choice.
My opinions, of course...
