Default Help with LS7 injectors

I just purchased the FAST LSXr 102 manifold and my old Bosch 42# injectors don't work.
I want to keep the injectors at 42#'s. Can anyone suggest an injector that will fit?
Thanks

thanks
the ls7s will fit, but 39's just not big enough
i'd have to run 65 psi to make it compatible
too much pressure= not good
looking at the FAST 50's
but want to keep it at 58 psi if possible, therefore the 42

I have the Bosch green tops rated at 42"# at 43.5 psi
If I understand correctlly the LS7 are 39" at 43.5 psi, maybe 42# at 58 psi.
My Bosch are 48# at 58 psi-that's what I want-sorry.
