I think we talked about this in the last few posts (other thread). If you want a good comparison, start with the same vacuum advance. The only change to make is use the ported source, unless that takes away too much timing at idle.
Since the vac pod is leaking, if weather and time permits, plug the vacum line and just experiment with the intial and mechanical. See how it will run with no vacuum advance at idle. That's what's going to happen anyway when you go ported. Its also what you'll need to do anyway to measure out the mechanical advance curve.
