Timing should be set on a dyno. While you can do a decent job on the street, the dyno will do a much more accurate job. Every car is different and for anyone to give a figure and you to rely on it completely is insane. I would start low with the 29deg your mechanic recommended and slowly work up from there. Has the distributor been recurved? If not it will probably not have the optimal curve for your built engine.

Do not use the timing curve or specs from your engine as anything more than a reference point. What that engine requires will be totally different.

Changing air fuel mixture should only be done with a wideband. How do you know it is running rich? There is no reason to not run it slightly rich as you are searching for reliability and the absolute total maximum HP. You probably also aren't worried about fuel mileage as this isn't your daily driver. I am assuming this is a CIS motor?
