Like Glenn said immediately above, your total advance should be in the 34 degree range and will be all in by 2000 to 2200rpm. It builds on your base timing, so if you set the base timing (no vacuum at idle) to 8 degrees your total timing might be 30, but if you set your base to 12 it would then be 34. If your base is now at 16 then your total may be up in the 40 range which is pretty tall, but might still be OK depending on your piston choice and cam.
