I just put a 2002 2.2l crate engine in my 2004 cavalier. Everything matched up fine except for one issue. It seems the injectors and the injector seats are slightly different in size. I'm using the injectors that came originally with the car. The crate motor had a different rail and injectors.The spacers from the 2002 motor are slightly larger than what was in my old motor. Will the 2002 injectors work on the 2004 rail? Or how would I get pass this?

Do they make the injector cups for the 2002 head (larger O.D.) that fits the 2004 injector (smaller)?
