So the head is on and torqued to spec(s).
I used a printed protractor posted by a forum member and this worked out pretty good with the help of my wife. She assisted in making sure the protractor did not rotate while I torqued the bolts down.

I've also installed the two sending units within the head. I applied high temp sealant and torque them to spec.

The cams are timed and I completed the installation of the cam sprockets. Tricky to understand at first but keep studying and it will come to you.
It's also important to lubricate all side of the cams and thrust spacers before installing them as they will be moving back and forth.

I began reading about the VANOS unit and discovered I needed to replace the seals and the outer ring since the tolerances were beyond specifications.
I've created another link if anyone is interested or will be performing a cylinder head replacement in the near future. Something you should consider since its already out.
