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.
