DSP, I don't believe that any loosening of the manifold nuts is related to them actually unwinding. Nyloc nuts won't help, but they won't hurt either. (They are heavier though, so there could be an adverse effect on performance!)
I think the problem here it is more to do with gradual compression of gaskets and the phenolic injector blocks than nuts coming loose.
