Header bolt torque specs

Anybody know the torque specs for the header bolts. After instaling my ASM's I never really retightened them and it sounds like I have an exhaust leak.

According to the factory service manual, make a first pass at 11 lb-ft starting from the inner bolts working out, and then a second pass at 18 lb-ft inside to outside. I also found that it is much easier to take off the front tires and inner fenders to access the bolts.
