The '71 240Z I just bought has an L28 (F54/P79) in it, complete with injection. I will be going back to SUs, but have a question, what manifold gasket? I've seen posts saying to just use a carb-type manifold gasket to cover the notch in the intake port. But I haven't seen any carb gaskets that have the later exhaust port shape for my P79 head. Am I not looking to the right suppliers? Is there a special gasket for this? Or am I just mistaken?

You can use any "round exhaust port" gasket. The holes are there for the FI, but they will be covered nicely by the carb intakes. I'll post a pic soon.

I just took this pic. It is a Fel-Pro gasket. You can see where the carb intakes will go. Good luck.

So the carb intakes have plenty of metal to cover the notch and still seal OK? I ask this because I don't yet have the intakes in my possession.

Excuse my ignorance, but just to avoid being incredibly stupid, do I need to use any adhesive or sealant when installing my carb manifold gasket? Or do I just bolt it up and go?

Cheers guys

No sealant or adhesive should be needed on a manifold gasket. The carbs are on mine now, and working well so far. Details on the car's web site, linked in the signature below.

Is that a square port 240Z exhausy manifold on a P79 head? How's that working out for you? I was advised that it was not a good idea.

I don't think it is a square port in the pic, but it's hard to say for sure. When I did the swap I used a generic round port gasket from a local parts house. It was listed as fitting all non-turbo L28s from '77-83. Worked (and still works) fine.
