The L29 cylinder heads won't need more than 30--32 degrees for best power. Perhaps not even that much.
Best economy is another story--but--because the chambers are fairly efficient, I don't think you're going to want the high-40s, low-50s even with the part throttle electronic "vacuum advance" adding advance.
A dyno would tell the tale. I bet ~40--42 is all you'd need.
