Update...
It seems i had more then one problem. I found the following issues while trying to fix the rough running.
- Bad power valve in Holley carb
- Vacuum leak (big hole) in vacuum hose
*** Then throttle ok but occasional rough running still a problem....
- Sticky intake valve..... (this was an older - late 60s - junk yard engine)
i added Marvel Mistery Oil to my crankcase oil and gas tank then, after driving for a few hundred kms, the engine is running MUCH smoother.
My car is fun to drive again

Well, the Marvel Mystery Oil did help,,, made it smooth BUT, only while i used it.
Got sick of adding it then tried, Gumout Regane.
That was the secret. Now after two treatments, my engine runs amazing.
