deadlift handstand

I can do a handstand where you kick one leg up without issue. I can also do an elbow or headstand from a deadlift (just lifting my legs up without any kick or push). Being trying to do the same with a handstand and feel like I'm close but just can't get it. So to those of you who can do this what is the trick to doing this. How far away should your hands be from the pole? how much of your back should be touching the pole and should there be any pressure on the back of your head when you try to raise your legs up. Any help would be appreciated!
