Demon's answering system should say advance the timing as it seems they tell that to everybody who calls in about anything.
IF YOU DO ADVANCE the base or initial timing be very aware that you will need to limit the total by recurving your distributor!!!!!!
Failure to do this can cause several very serious consequences!!!!

Most Holley and Demon problems are in the base plate area, not floats, not timing, but simple setup of idle speed and transfer slot parameters along with accerator pumps and pump cams
