[C6] WTB 57/60lb injectors

[LS2POWA]

Looking for a set(8) of 57/60# injectors. Shop who built the motor used repunched 42s and they will not hold up for what I plan on doing with this car. Ive come across a new set for 360/370, wondering if anyone knows where they might be had cheaper? Would love to find them so I can finally get my car tuned and actually have fun while not blowing through 18 gallons of fuel in 4-5 days, if Im lucky.
