Hey guys it's been a lil while. Still doing some work on project pat. Was talking to a guy with a Nissan medalist . And he was saying that with maybe a lil rework, a RB25 head might work with a P40 block. Can anyone here enlighten me on the possibility

Rust is just natural weight reduction.

I can't see how it could possibly work.
Head bolt pattern is different, I'd bet the bore spacing is different, RB head is SOHC or DOHC, P40 uses pushrods.
The only way I can see that they're close is bore size, RB is only 0.3mm larger.

Any fuel injected head can be used?

The standard head will work.
You can place EFI injectors in the throttle body or intake manifold.
