If you have a 502 with a Thunderbolt IV ignition, factory is 32* total advance. Running 34* will be fine too. I doubt you'll see any real difference.
If you are talking about a newer EFI 502 with a TB V, tthen I'm not sure what total is. They do add timing differently than a TB IV. They work in conjunction with the knock meter and when any detonation is sensed, it retards the timing.

Make sure you check it higher than 3200rpms. Some modules don't give full advance until 3600-4000.
