The injectors on the rail from the 3.4 should work fine.
The injectors from the 2001 should work fine too.
The change to the non-return fuel system occurred in the 2002 model year. Injectors should be the same as 2000 & 2001 except for the second notch missing on the later injectors. The main difference is that the fuel pressure regulator is in the tank as part of the fuel sender unit rather than at the rail on the engine.
Ike84 did an interesting thing a few years back: https://986forum.com/forums/diy-project-guides/80079-986-2-injector-retrofit.html
