98 injectors or 02 injectors?

I have both the 98's (pn 12554271) and the 02's (pn 12561462). What are the differences between these years?

Which would be better for my application? I have a 98 Trans Am M6 with a LS6 swap (388hp 375ft.lbs)... I already have the car tuned for the 98's but will it hurt me or be better for me to put in the 02's? or are the 98's fine? or are they both the same?
