I just got remanufactured heads for a 2000 passat 2.8 30V ATQ engine from a machine shop. The only problem is that the place where the code is located on the heads are worn down I guess due to them being machined. The only number I have is a casting # of 078 103 373 AH and 078 103 374 AH. Can anyone verify if this is the number for an ATQ and not an AHA? I don't want to put the wrong head on.

 

You... Ummm... do realize this is AUDIforums, not VWVortex, right?
