Check this post for the specs.

Lower Intake:

1. Use a skin coat of RTV silicone on both sides of the water passage ports (outer most holes) and put the new lower intake gaskets into place
2. Hand tighten the 13mm head intake bolts and Torque the bolts , starting from the center and working your way out in a circular pattern
3. Torque these bolts in a few small increments until they have reached 250 inch pounds of torque.
4. Upper Intake Plenum:
5. When installing the intake air plenum , be sure to catch the four center bolts and the two side bolts (stiffener brackets) before tightening , The center bolts should be torqued to 250 inch pounds .The fuel rail bolts should be torqued to 100 inch pounds

they are in the factory repair manual.

Found this info, it says 88 inch pounds. Hope it helps.

if this has a plastic intake these have a problem with the intakes warping allowing coolant into the combustion chamber.the only fix is to replace the intake manifold and gaskets.make sure the intake bolts are tight and torque to specs as if the bolts are loose/broken or not to torque then the intake can cause coolant to leak into the cylinder because the gasket is not sealing.
