280z exhaust manifold confusion

So I have been researching and I am a little confused. On zcardepot they list the intake and exhause gasket as being able to fit years 75-83 including turbo models.
https://zcardepot.com/engine/gaskets...DESC&limit=128

How is that possible, I thought that the 280zx model l28's had different shaped exhaust ports. Does that mean that for example a p90 exhaust manifold could bolt on to a n47 head?

I would get a gasket that matches the cylinder head.

All the pictures look the same and when I rebuilt my engine it was the same gasket for a number of years, but it fit fine. Nevertheless, MSA gaskets look like they are less and part numbers broken up by head style so I would just buy one of theirs.

square port exhausts can fit either kind of head, but not vice-versa, if I remember correctly.
