v8 injector / inlet manifold removal

[johntom]

Hi
i am about to remove the intake manifold from my 400se (to replace with a gas flowed one, courtesy of fleabay). Just wondering about the procedure for swapping over the injectors from one to the other. I know the top end of the injectors are secured to the fuel rail via 'o' rings (new ones on order), but what about the bottom end into the manifold?
any tips welcome!
