Maximum advance curve on my 360

As noted before, With the timing at 14/35 with 30% AV gas aditive on top of the 98 fuel I ran best time of 14.35 seconds. With the the dizzy recurved to 12/27, straight 98 octane fuel, best time was 14.21 seconds with the the 318. Did not lose anything. In fact it had a little better response. If you can advance the engine to just before detonation, whether it is 27 or 35 degrees, Do you think this is an optimal setting for your engine? Can someone vouch for that? Or advise me otherwise please. Just more food for thought.
