Any dyno numbers from the headers?

The intake and maf arent really restrictions till we start putting a lot more power down. And yes i know a more aggressive cam would help but i wonder how much considering my car didn't respond to the ls6 cam. I want the shop to do it because i know they will do a great job plus i work everyday and cant be without my car for the 4 or 5 days it would require for me and my friends to do it. Also i have a feeling that whole intake crossover issue and welding of the downpipe will require a little more know how than i have.
