80% of Eldar infantry, and even a few examples of Eldar Vehicles (Wraithlord, Eldar Titans) have pointy heads. They're not mutually exclusive to screaming bitches howling banshees.

Comic 463 is up. Yes, these are Adeptus Custodes.
And in case you're confused about the dialogue, the flashback sequence is played out as Rand is narrating it. So where Rand would say "Marnia introduced us to the Custodians, whose names I don't remember" in real time, in the flashback, Marnia will actually say it in the flashback as normal, using fill-ins for the names.
