Manifold bolts, how tight?

[dapper]

Anyone know how tight to torque the exhaust manifold bolts on a NH3430? I am changing out the vertical exhaust, and will be replacing the manifold, and can not find this info.
Thanks for your help
Dap.

Use the standard torque value for the diameter, pitch, and hardness of the bolts. Should be about 30 ft/lbs for 3/8-16 grade 5.

Thanks again.
