Cylinder head removal. 2.0 d4d

[kevinf]

attempting to remove the cylinder head and got as far as removing the injectors,

noted the strange looking banjo bolts on the fuel leak off rail, I thought that I needed to use a 6 mm Allen key to remove the banjo bolt, but only removed a blanking plug

will the banjo bolts screw out of the injectors as you would expect and if so what’s the blanking plugs for

thanks
