No matter the frame, stock truck manifolds likely won't clear. I used trailblazer SS ones and it's still tight. Good luck!

I have a stock frame AD truck frame and the TBSS ones mentioned above still need some clearance like he said. More on the passenger-side than the driver-side because of the AWD of the SS it flares out more. I have some pics somewhere of my 5.3 sitting in the frame and the manifolds on if anyone wants to see what I mean. I also tried Corvette manifolds which would still need clearance but for me in a more inconvenient spot. Oh and the SS manifolds help keep your steering linkage cleaner than the Vette ones would have.
