    Installing header on my 05 chevy silverado 2500HD and was not sure what to torque the bolts down to. Any help will be helpful.

    Use the torque specs that came with the header's,if you don't have them, it's 18 ft lbs for the 6.0 and 26 ft lbs for the 8.1 Don't forget to retorque them after a few days as they will loose some of their torque after a few hot/cold cycle's.
