2003 Silverado 1500HD upgrade help?

[6.0HD]

Hey what's up, currently I'm driving a 2003 Silverado 1500HD 6.0. I want to beef this truck up and make it more powerful horsepower wise, and I've been looking into some things for it. I plan on putting a k&n cold air intake on it, and I'd definitely like to put new headers and a cam in it, I'm just not sure what to get for that. Anything you guys recommend? A supercharger is a little above my budget, so that's not possible, but any reccomendations are appreciated.

I have learned comp cams is great for helping you dial in your wants, and you talk to a real person.

 

My only short list (I build everything since 1979), some stainless headers on the alloy... but there is an all iron one I'd leave the headers alone.

I assume yours is all iron?

Long tube headers and a tune.
