Nice numbers ,will this headers fit on the awd 6.2 denali?

 

The headers will fit all the late model full size GM trucks and SUV's, but use a couple of different "Y" pipes depending on the engine. The Sierra Denali and Denali SUV both use the same part number, but I would call the mnf just to verify. Don't forget, if you install headers it is highly recommended that you follow it with a tune to get the most out of your money and to keep the "check engine" light off.

 

would also like to know which cam you used? good numbers man.
