-4 is a "head set" while -1 is the head gasket only. The Head Set contains the same head gasket as well as the manifold gaskets, rocker cover gasket, and some other small seals and gaskets
The only Datsun head gasket I had fail of itself was a Fel-Pro PS (Printo Seal) -- it leaked coolant. That was some years ago and the new ones are PT with PS overlays. 21199 PT-1 is much better looking to my eyes. The A12 photo above looks to have the older-style Fel-Pro Printo-Seal
