If you are talking about the yellowtop injectors with a black body that ford used on nearly every 5.0 from the 90s through early 2000s then yes, they go in just like stock, you can even use the retaining clips

I bought a set of "Blue Top 24lbs" Ford Motorsport injectors for my IROC. Worked perfect! http://www.fiveomotorsport.com/

I'm talking about the older yellowtops that look similar to multitecs. Afik the orange bosch III injectors that newer fords use are 30lb, don't quote me on that though.
