The Project Pad

Folks,
I've got a head with what I believe to be a Blau 272 cam...
How would I confirm that?

Do they have any markings identifying them? This cam has the VAG casting marks; were blau cams regrinds of factory units?
Thanks!

Well, I measured, and the cam I have has a lift of 10mm or so. Guessing it's a stock cam, as the blau 272 is supposed to be 12mm as far as I can tell.
