Iron heads typically like 36° total and aluminum heads 32-33°.
There isn't a lot of difference in results though. Drag cars get faster trap speeds by backing off the total ignition advance.
These days you can compensate to an extent for detonation by modifying the "dynamic compression" with camshaft timing. What it does is blows compression out of the exhausts by leaving the exhaust valves open longer.
That usually means more overlap of the intake and exhaust being open at the same time. Milder cams will tend to "detonate" while more radical cams reduce or eliminate that.
I can't tell you what those numbers are. You need to use the "dynamic compression" calculator on your camshaft timing events to determine that.
