In edit mode if you press Alt+H you see some vertices appear that you had previously hidden. If you don’t want them, delete them.If you change to smooth shading (button in toolshelf) you will also see dark lines on your model. This occurs when you have some inverted normals. Select all faces and use Ctrl+N to recalculate their normals

wow thanks
