16v Cam Identification

I have a set of cams that came in my 2.0 16v, the block is originally a 6a but I believe it has a KR head.

Does anyone recognise them?

The markings are:

On both:

027 ——–  VW/AUDI STAMP ———– WTR


On the other side of the exhaust:

1 ————- U

On the other side of the inlet:

5 ————- U
