Head Bearing part number change
In looking for replacement head bearings for my 91 K100RS, I see that BMW dealers (a few) have changed part numbers from 07119985070 to 31427663941. The new one is about $75 while I can still get the older one for about $30. Both are BMW parts, at least the older one is. My question is, is the later one really worth $45 more a piece? I am wondering if there were any quality issues with the older one. Any comments would be appreciated.
