Actually Kevin [et al.], the factory says not to use anti-seize on the Nissan K21-K25 engine, it can cause 'cool spots' where heat transfer is not as it should be. but you are very correct about the correct plugs not sticking down into the head the way he plugs did on the 4gMitsu series engines which should have anti-seize on them as they do have a couple of threads that do stick down into the combustion chamber.
