When to upgrade injectors

I have a recently upgraded cam , titan iv cam, with 243 heads now, don't know what kinda power it will make but I'm wondering I'm getting close to the limits of my original (114k miles ) injectors and if so will 36lbs be ok,
Also who are you getting them from ? Are they from a newer gm performance car ?
Thank you

Have you tuned it yet? The tuner will be able to tell you the duty cycle of the injectors(how hard they're working). Anything over 90% better get bigger ones.

you will easily max the factory injectors (especially on a old weak pump) with those mods.

LS 9 Injectors

Would LS 9 injectors be an option on an LS 1 engine
