Fuel injector size help vortec v2 SC

What size fuel injector is recommended for this mod?
I know stock is 19lb.
Is 39lb appropriate?

Also, you want your duty cycle to be a max of 80%. Anything higher than that and you could get fuel starvation (lean out). Anything less than that and you could run rich because the PCM won't compensate for it.
