Pretty much anything with an LS in it at some point had these heads.
Look for an LS6, L33, LFA, LC9, LS2, LH6, LS4, and pretty much any other H.O. engine.

Which year silverados for sure had these heads because they have a lot of 2005 and up Silverado at my local junky yard

05-14, but its going to depend on which engine they had.

Well they have 6.0, 5.3 and 4.8 I just want to be sure they have the heads.

Unless you start pulling Vin numbers, you're not going to know.
They were an option based on what engine was in it. Only in things like the Z06 corvette and LS2 GTO are you going to be sure they had those heads.

6.0 if they are the 400 hp models will have them, kinda doubt 5.3 or 4.8 will. I have a Trailblazer SS engine that has them.
