You might have a problem find
You might have a problem finding something that matches exactly what you need. What I did was research a bunch of different ignition settings from different cars I found on the internet, then kind of blended them together for what I'm using.
Take a look at my ignition config under the 'files' section. Now, this is for a boosted car, but for your case you can ignore everything above 100 KPa engine load.
Ultimately, what you want to do is get something that works well enough to be drivable, then take it to a dyno and refine it further.
If anyone wants to volunteer their own ignition configs, please feel free to upload them under the files section!

a rough guide
as a rough guide to get you going could you not use a timing light to extract your current dizzy's "map"? Simply rev the engine to set points (e.g. 1000, 1500, 2000 etc) to get the advance at each point and use these figures to create a basic 2D map.
You can then tweak that map by advancing the ignition when the engine's not under load by up to 15 degrees when under no load at all. This will improve economy.
However, there's no substitute to getting to a rolling road and mapping it out properly!
