According to All Data the Lower Intake Manifold to Cylinder Head Bolts are Torqued to 11 Ft Lbs. Use thread lock compound "lock Tight" on the bolts to ensure they remain tight. On the Upper Pleneum bolts Apply thread lock to the bolts and torque to 89 In Lbs. Foot Pounds on the Lower and Inch Pounds on the Upper. Always use a tap or thread chaser on all bolt passages and bolt threads before attempting re installation. There is a torque sequence to follow on the upper and lower, be sure you get that to install the intakes evenly. Also it is best to tighten the fasteners in 2 or 3 steps to ensure an even installation.

Make sure you use the right tightening sequence too. 89 inch pounds is for the upper intake or Plenum. 136 inch pounds is the torque specs for the lower intake
