No that's an ADU, ABY and AAN will be in same location but with ABY and AAN as the beginning of the code
Duh. I *know* that. But you said of the AAN vs the ABY heads that "Pretty much identical other than the engine code stamp on the back." referring, I thought, to some markings on the ABY head. I am confused? What did you mean? Do you have a photo of said "engine code stamp on the back"?
The reason I am pushing the point is if there is some new info, I would up date my AAN Engine Numbers: Location and Engine Build Dates post with the new info. See link:

basically wanted to know if a 96 AAN head is the same as a ABY
See, if you had just asked the real question, you would have got the answer you needed: YES. But hey some people will have learned something else along the way.

The cam gear on the right is interesting, I didn't realise they used different size gears let alone split gears?
I have an original Audi booklet on the 7A engine and it claimed they had sodium filled valves, but i wouldn't be surprised if only the early cars with the tubular manifold got them.
Yes, but you can use the tuna can hall sender or just weld / drill, tap and bolt a bracket on for the front pulley type hall sender, so essentially they are the same.
But to drive the tuna can hall sender, you need to have the intake cam with the drive gear as well.

To date I have never personally come across a post 1990 16v KR or an I5 7A head that have sodium filled valves the part no. on those heads are 027 109 611D where as the sodium filled ones are the same part number but a B on the end for the 3B, ABY, ADU and AAN or the earlier Pre 1990 16V KR heads.
