Perhaps my march 2006 manufacture date leaves me in a different situation than you later model year 325/328s. Any advice or knowledge that can help here? I have been quoted $1100 for the valvecover alone but want to acheive two birds with one stone and create a 'true' 330xi at the same time. Thanks ahead of time guys.

Both the '25 and '30 engines have the same head (part numbers are identical). They have double vanos and single valvetronic.
