Well I have done it with a new gasket and left out the bolt under the inlet manifold, with no leaks.
of course nissan put it there for a reason, to ensure no leaks, so not using them means there is a chance it won't seal correctly.
I still don't understand why you think that if it leaked some coolant becsuse the bolt wasn't there why putting the bolt back in wouldn't seal it up? cooant leaking past the gaskrt won't destroy the gasket.
Anyway, it's up to the op of he wants to risk it.
You think it won't work without the bolts, I know it does work without the bolt under the inlet manifold at the front, with a new gasket and no leaks.
