Well I'm getting my car back today after the head replacement. I'll report back with the results. Does anybody have any info on a difference in part #s for old and new head design? I admit I didn't search for this info at all, just came to mind. On a side note, the courtesy 2009 328i I have from Monterey BMW has a valve train that taps louder than my car did. I'm a little discouraged that an obviously newer head is doing the same damn thing.
