UPDATE May 1st 2017 AM:

I drove the truck yesterday and the noise coming from the front of the rock cover is louder.  I need to figure out what that noise is.

It sounds like a loose rocker or valve lash? It seems to be just one or maybe 2 valves, louder near number one cylinder.  I hope its not a valve, valve seat, or spring.  I will try one more time on an adjustment on the valve lash, and open the lash up a couple thousandths. 

I'm going to carefully inspect the rocker rack, lash studs on valve stem location, and remove the camshaft.  I haven't decided yet, but I am leaning towards a new camshaft from CompCams - the 252S.  At this point, I'm concerned about the overlap in the 261C, but it's just my gut feeling, past reports on this cam in a 22RE, not based on any real hard facts.

Regarding the fuel pressure regulator... it's looks impossible to R&R without removing the chamber from the intake manifold.  But, I will replace it.

1986 XtraCab SR5 22RE 5speed W56B, ~26,000 MI after break-in, DIM (Did It Myself) rebuilt engine - .020" over, engnbldr RV head, OS valves, 261C cam, DT Header.
