Nope, no grinding...  I've never seen hand engraved numbers "scratched" into
a stock VW cam before...

No stock cam I've seen has different exhaust and intake lifts though...
It's definately a VW casting, but I don't know why the exhaust lobes have
less lift.  A stock g-grind has .423" lift on both, the n-grind has .405"

I guess I'll slap it in and see if my butt dyno can tell which one is
better...
