It is covered on ls1howto.com, but basically it is a tighten until 22 lb-ft on the rocker bolts but the rockers should be on the base circle of the cam. So with the crank at TDC you do specific rockers and then rotate one turn and do the others. I would also turn again and re-check and then one more time and check the last of them.
