I would work your way up to the 36 at full advance, with today’s gas that may be a bit much.
Suggest timing at around 34 full advance, and then see where that leaves you at idle. All with the vacuum advance plugged so as not to leak vacuum nor impact the distributor. Always lots of debate on the vacuum advance, I do use them and fine that they help driveability at low throttle situations, but that seems to be personal preference and very much tied to what cam and carb combination.
You said full advance at 2000 rpm. That might be where your distributor finishes or it might not, you need to go higher and figure that out first. Might be more like 2200 or so.
I am assuming by your posts that you own or have access to a full advance timing light? One that you can see where it is when at full advance? If not, get one.
