What is the proper way or sequence to installing the valve cover.......I was reading a post that said it was
possible maybe it was installed wrong or maybe referring to the bolts securing the cover......Is there a
sequence when tightening the bolts for install......

 

Here is valve cover bolt tightening sequence and torque values. I've replaced 3 valve-covers with this information with no issues.

 

It looks like 3b is for the exhaust camshaft sensor, not the valve cover.

 

Keep in mind those torque values are pretty low. All you really need is to seat the gasket so it doesn’t leak. Go too much on the torque and you could make it leak, or crack the cover. For the cover, it’s finesse over tightness.
