Default FAST 102 ... Which Injectors?

I am preparing for a heads, cam and intake swap. I now have everything needed (I think) for the swap in my ls1. I am giving my intake a quick dusting of new paint as I want it to look new. I have a set of FAST 36lb ev1 injectors along with an ls2 style fuel rail. Can I use these injectors or do I need to go out and replace them with ls3 injectors? Yikes, the bill never stops 😜.
Thanks guys..

They should work I think although I used BBK rails on mine. I got 42# greentops to work which was said not to fit by an easy Dremel of the FAST to clear

measure the injectors i believe those are 2.5" injectors if so they are the correct size and nothing else is needed for the setup. if they are ls1 style 3" injectors (oring-oring) then you will need spacers for the rails

Do you have a LS1/6 102 or a LS3/7 102 because this is the Gen 3 section. If its a Ls1 you can use your stock injectors in the 102 w/ and adapter set.
