OK here's the skinny -- and I still cant believe it
As I said I checked compression, rechecked timing, etc and when I got everything back together its still got a horrible miss and very loud clicking. When I just did compression, no noise.
When I R/R tbelt, I put in new plugs PFR6B and a new set of coils in the back. I usually do this if I have coils in stock -- which I did; a new set of 6. I Always have plugs in stock, got em from Rock Auto on sale a few years ago.
Long story short -- one each bad plug and bad coil -- BOTH NEW! Plug has hairline crack in insulator that you can't see until it arcs over. Coil -- primary side was good, but high voltage side has intermittent OPEN which led to no spark, and when it did spark, it arced badly from the insulator-- THIS IS A BRAND NEW COIL I've had in stock for 5+ years. Note -- Coil and plug NOT MATED on back bank.
I knew the ignition modules were good and I did ring out the upper harness on the bench during the course of tbelt change. So the combination of bad plug (causing the miss) and bad coil (causing a miss as well as a huge arc which sounds atypical for an arcing coil , it is the source of the bad tapping sound) caused me to R/R rear plenum at least 5 times, maybe 6 but I FINALLY found them both and got it right. Motor is whisper quiet now at idle and steady as a rock, just went for a little Italian tuneup and I am back in business.
Total here -- new tbelt idler, new tbelt tensioner bearing, new serp belt idler, new tbelt, 6 new spark plug well gaskets, and I will say 12 hours of tbelt change time, and 12 hours troubleshooting this ignition mess.
Moral of the story-- just cause its new doesn't mean its good. I'm good to go belt wise another 30K miles.
