Hey, I was wondering if someone could help me. I have an 04 Silverado 5.3 and want to get headers. Does anybody have any suggestions for me?

Try and find some longtubes!!! If not then everything else is pretty much the same as far as power gains go. If you want to get some reliable ones then go with either... edelbrock, gibson, hooker, tog, ASM, Dynatech. Dynatech makes an entire system besides the cat back part. But it goes from header, through y pipe!!
