16v HEAD??

[CIAPU94@aol.com]

Hello.
I am wondering if audi has made a 16v head for a 4cyl. motor?
I have a 924 turbo. I was told by some one that he once found a 16v head that 
woudl fit perfectly on it a few years ago. But he doesnt remeber which head 
it was although he said it was a VW or audi head. I went to a salvage yard 
and checked the only 16v head i Knew of from WV, which was off a 16v 
scirocco, and put my 924 head up next to it, and the 924 head was 
significantly longer and a bit wider. Now i am wondering if perhaps audi made 
a 16 V head, and if any one knows if there is one, is it bigger than the head 
on a 16v VW, and will it possibly fit my block?
the piston diameter on a 924 is 86.5 mm, if that helps give any idea of the 
size of the head.
By the way, the block on the 924 is the same as the audi 100 sl(not the late 
model 100 but the earlier one like around 1979), and also the VW LT van. i 
dont think those car were ever imported into the us.
If any one can give me any leads id appreciate it very much
Thanks in advance
