I have a E39 M52 Cylinder Head with valves that has never been installed for sale. It is remanufactured, and ready to install! All you have to do is swap your cams, which I can help with if you live locally (San Diego) or provide you with instructions on how to do yourself (very easy). I would like to sell it for $900, but I am willing to accept offers. Let me know, as my fellow Bimmerwerkz members are all considered friends and I am willing to give you a good deal. Email gsrmike@msn.com and we will talk. Thanks!
