Those are the replacement for SVO red tops, Ford replaced the red tops and green tops with red and green skinny injectors. I know you said your having it tuned by SSP but for those doing their own work the flow is similar to the older injectors but from what I understand they tune slightly different. I had a buddy swap out green top svo's for a new set of green skinny svo's without changing the tune and it went very lean (mid 10 second car lost 1/2 second). We havent retuned it yet so I dont know where they are different, he just swapped back to the old green tops and all went back to normal.
