Advice on 2.0 heads please Options

[Creamsicle New Zealand]

Hi everyone, I have been offered a pair of NOS 2.0 heads but I do not know what to look for. I don't need them but if you folks think they are cheap and good then I would buy them and store them for any future use/need.
I have got photos of them on my phone but I cant put the image here.
The person selling them is a friend of a friend.
Details on the box STUECK 923 104 016 00
Stamped on the heads - 039.101.371A with VW symbol
Sellers says these are the later style heads with the air injection port in exhaust port and he says they have more meat under the exhaust seat.
He is wanting USD$1400 for the pair. What do you guys think please?
thanks Steve

I'd have a close look at the mold marks. Castings / molded parts usually have a number to show what mold they came from in the event of a problem during the machining process.

If all of the mold numbers are the same or not there, I'd tend to think they are modern replacements. Given these heads were made in high volume, having all mold number marks in the batch the same would be near impossible.

If mold marks don't exist, I'd have a close look at the part for various artifacts, ( marks ) if they are the same that would tend to make me think they are modern. Reproductions are likely to be made in small batches from the same master.
