Default Injectors for LS3 OEM intake

I picked up a used LS3 intake and I bought Holley 160lb injectors, but i feel like they are too wide for the bore in the intake.

They seem a little loose, which i know I can swap orings. But I feel like the nozzle should be in the port more, no?

LSX B15, Procharged, E85, Dominator, EV1 harness.

You just need larger lower o-rings for the fuel injectors. You need these:

I had the same issue with my BTR Trinity LS3 intake with Holley 120 injectors used those o-rings and problem solved
