Default Do I need Larger injecors?

I am rebuilding my 2006 Z06 motor. Should I get larger injectors? The old motor did 550 whp. I fell this one will be closer to 600 with the atomic intake on there. These are the components
  • Mast Motorsports Black Label Cylinder Heads 305cc
  • Lg motorsports G7x3 camshaft
  • Comp 4130 pushrods
  • Comp timing chain
  • Comp trunion bearing upgrade
  • MSD Atomic intake Manifold
  • LG carbon intake system
  • LG super pro, long tube header system

Not necessarily.

I've been using stock injectors in my LS7 drag car since 2009 without any issues, even though I'm between 95 and 100% IDC.

The car's never been dynoed but it's probably around 600rwhp based on my best ET and trap speed.

Ask your tuner where your duty cycle is on your injectors.
