Default Injector advice

01Z. Going with H/C/I, long tube headers. Do I need bigger injectors? If so what do you recommend?

You probably will need more injector. I did.

I went with rebuilt GTP injectors. On the LS1/6, they flow 42lb, which is just about right for a H/C/I car. Price is right too.

You will definitely need larger injectors, more than likely in the 36-45lb area. The head and cam spec will determine what will be close. Also you will have to have someone tune the car who knows what they are doing. In tuning you will need to have the entire rpm range balanced, making sure the injector flow rate, etc are in line. When you get new injectors make sure that it comes with all the flow values and the Duty Cycle is less than 80% at WOT. When they start quoting flow rates make sure they state at what pressures--3 bar or 4 bar. Good luck in your upgrade.
