Hello im new to the form but i have an 05 h2 and motor wise everything stock, flowmaster kit what else are people doing to get more horse power out of these 6.0

 

Howdy and welcome to HF Rich.

Head over to the H2 section if you want to pursue your tech questions.

 

The 6.0 is basically another LS motor from GM.

So it all depends on how crazy you want to get

You can swap heads, cams, etc

Right now a custom tune would help some for not too much cash and an always be updated later as you ad more things.

HP tuners is a popular tool some rookies and a lot of professionals use to tune LS engines among other things.
