I guess I had some bad information. It is a 2011 Suburban 5.3l with 15 bolt heads. In that case, it should be the heads with the 2nd design bolts, and I already have that torque sequence and values, unless the bolts were redesigned again between 2008 and 2011.

Am I correct that the bolts were redesigned and not the head or block? In which case, if I were to work on a 99-04 engine, I should get 2nd design bolts when I replace them (since they are TTY bolts) and use the 2nd design torque procedure?
