Anecdotes can be a good starting point.Several people, including myself have reported success bottling with .25 inches or .5 cm head space.Bottles without headspace are likely to crack during bottle conditioning. A little bit a of air is necessary for the liquid to expand if necessary.
Knowing the specific type of bottles, and confirming their durability for being used this way, could be a helpful next step.
