Have you tried changing out the o rings? A buddy once used my injectors(2005 5.3) on his(2001 5.3) intake, and they didn't fit. He had to use his original o rings. My o rings were thicker than his if I remember correctly so they didn't want to seat on the intake.

went and compared the intake/fuel rail to a 2002 5.3 silverado intake/fuel rail and the intake is exactly the same
but the fuel rail was different. Swapped the fuel rail onto the intake and it worked with the stock injectors
