Pelican Technical Article: BMW Head Gasket Replacement
A few pointers:
There are 3 small torx bolts at the front of the head- dont miss one or you will damage the timing chain cover/the head wont come off. The timing chain guide sticks up out of the block - dont break it when removing/refitting the head. Make sure both locating dowels are in the block. If you are taking the cams out to have the head pressure tested/skimmed, read the pelican parts article on cam removal or you risk snapping the cams.
