I believe ALL 11mm are mechanical lifters and will not have 2 drains "humps" up front...only one in the center.The 12mm will all have the triple square bolts and the 11mm are hex drive. *Edit* To see that look through the valve cover oil fill or take the valve cover off.
This is a picture of my Hydro. lifter head. You can see the 2 holes at the top those are the oil drains. The little one on the left won't be there on a mech head. The "humps" are when you are looking at it this way. The little hump by #2 injector isn't there on a Mech. head.
what year is the engine supposed to be?
seems like everyone with limited VW knowledge, always tells me the casting number on the head instead of the actual engine code. lol
