You have a connector for the air pump crossover pipe at the front of the engine and they should be at the back. There should be plugs at the front. You may have swapped sides from their original locations when you put them back on ... but that's OK because they're the same.
If you plan on keeping the air pump you'll need to swap the plugs and connectors around. If you're not keeping the air pump just put factory plugs front and rear.

What you had across the back of the engine was a pipe that connected these two points together, and were fed by the air pump. The air pump draws air through a filter, pushes it up to a pipe on the top of the motor, which goes towards the rear and feeds the points at the back of the head. Those drillings communicate with the exhaust ports via small holes, which you can see if you look into the ports.
To remove the air pump you remove the filter, pump, hose up to the steel pipe and vac operated control, plug the vacuum to that control, and remove the pipe across the back. All you'll be left with is the two threaded holes in the head, which you plug with the same plugs as on the other end of the head.
In the pic I have arrowed the connector nipples that you need to unscrew and replace with exactly the same plugs that are fitted to the other end of the head, in the same relative locations.

Here's a snip of PET parts diagram for the air injection system. The threaded connectors which go into the back of the heads are arrowed. You remove just about everything in that diagram and plug wherever it connects to the motor.

The car was almost done...
BTW, a new water pump will be installed. I'll try to take a picture from the old one today.

jmartins....just went through your photos...remarkable "save". Looks like you have done just about every difficult job in the books short of a complete engine overhaul, paint, seats, interior, pulled the engine, replaced head gaskets, on and on....great work!

Great work ....
Maybe someone else took the air pump off already, and you only need to get rid of what's left.
Keep asking questions and posting pictures ... we're all looking forward to seeing your completed project.

Make sure what you used for the fuel lines are rated for higher pressures for fuel injection systems. Not for lower pressure carburetor ones. Many 928s have been burned to the ground from not changing the fuel lines or using wrong ones for the injection system. 30R9 is the correct one rated for fuel injection systems. 30R7 for example is not.

Jose, a tremendous effort! Thanks for rescuing a car that most, including me, would have sent to the wrecking yard. Your work is outstanding and I look forward to seeing pics of it running.
I also looked at your photo album, super pics. I enjoyed seeing the family picture. The boy in the middle has that look in his eyes that says he will be the one who enjoys the 928 the most
