That's the bit the water hoses and connector go into? If so then it will come off after removing the screws, however they can just be tight. If there's any gap between the black part and the water jacket you may be able to carefully tap a flat screwdriver in and pry it off. If that doesn't work you'll have to try something more imaginative, possibly involving a hammer...
Watch out for the O-rings beneath the coolant hose barbs - you don't want to loose them.
