Ilford County High is a boys' school and Woodford County High is a girls' school, so there's no point in applying for both!
You don't need to live in the catchment area in order to apply, but both grammar schools are very much oversubscribed (about 850 applicants for 120 places, in both schools), so although it is theoretically possible for an out-of-catchment child to get a place, in practice it never happens.
I see you have also posted asking about 11+ study materials. I have a few packs of VR and NVR papers - I will make a list of what I've got an PM you later.
