On my '80, the dynamic timing is supposed to be 23deg. , however, after some experimentation, I found it runs really strong at 28deg. I was curious, so I checked it at idle, with no vac advance,.... Lo and behold a static timing of 8deg.
(the same setting my old GTO, and ski boat used). Usually the smog guys will retard timing to get a lower emission level. Unfortunately, this also sucks up your power . Just my 2 cents.

Yes Advancing your timeing will always smooth out the idle.
Here is an old hot rodders trick
When you hot-rod an engine, change cam, compression, ect the timeing goes out the window. The stock specs are NO LONGER ANY GOOD
SO!! heres the trick
Hook up a vacuum gauge to manifold vac
Advance the timing for max smooth running, as you go to far it will get rough and pop.
NOTE the VAC ... lets say its 24 deg at idle.
retard till the vacuume is 1.25 to 1.5 inch's of mercury less (22.5) and you will be really close.
test drive under full throttle to make sure it dose not ping.
If it does, back it off a hair more.
That was my race setup and it always worked.
