Fuel Injectors

Hi guys i've just got hold of some new fuel injectors they have the same part number on as mine but they dont have the nozzle bit on the end,  do you fit them as they are or do you swap the end bits over?

I managed to pop the end off one of my old injectors to see how easy they come off, and it was easy, well compared to getting the old injectors out the head LOL, as i managed to snap one in half, hence the new ones.

Just need to check before i fit them as i don't want to ruin my engine with bits falling into it, as i've only just finished my 2.0 conversion.

Thanks steve

Do you mean the shiny bits? if so none of my 8 valve engines have ever had these, only seen them on 16v engines.never tried removing them.
