Completed this two nights ago as described in the achievement guide. Loaded the Ark and using the sniper kept shooting heads until it popped. I was grabbing skulls and got this without knowing it. So, I'd try loading that level, from mission start, grab enough sniper rounds as you can carry and start popping heads. I did hit a few body shots, etc., and it still popped after 10 headshots.
