When buying injectors, keep in mind at which Fuel Pressure PSI they are rated at.

Theres lt1 FP and LS1 FP which are different.(43.5psi /58psi)

...so an injector that is rated at say.. 30lb/hr at 43.5psi is equal to 34.64lb/hr at 58 psi

I had Racetronix 37# ones (43.5psi rated) and they worked out to about 42#@58psi in my old LS6 with a big cam and almost all bolt ons, and my duty cycle on them were fine.
