What is a truck with a points distributor and a Holley carb doing with a carbon canister any way?

I would just go the rest of the way to smog free and disconnect the carbon can and use the vacuum line for the vacuum advance.

If your base timing is OK now then hooking up the vacuum advance will not require any changes to the tune.
