- Position the rocker arms in their original locations and tighten to the proper specifications.

- Install lower the intake manifold attaching bolts. Apply sealant or equivalent thread locking compound to the threads of bolts. Tighten the vertical bolts first, then the diagonal bolts to 115 inch lbs. (13 Nm).

- Install the upper intake manifold and tighten the mounting bolts to 18 ft. lbs. (25 Nm).

Hope helps (remember to rate this).

Toquer on the intake


start in the center working in an expanding square pattern crossing over the manifold on the first 2 bolts. tighten in 3 steps. these are low torque fasteners, don't over tighten & use locktite.
If reusing the fasteners, apply threadlock GM P/N 12345382 or equivalent to the threads of the lower intake manifold bolts.
Install the lower intake manifold bolts.

Notice: Proper lower intake manifold fastener tightening sequence and torque is critical. Always follow the tightening sequence, and torque the intake manifold bolts using the 3 step method. Failing to do so may distort the crankshaft bearing bore alignment and cause damage to the crankshaft bearings.

Tighten the lower intake manifold bolts.

from front of engine tighten 2 bolt back left side, then 3rd bolt back right side, then 3 bolt back left side, then 2nd bolt back right side, then back bolt left side, back bolt right side, then front bolt left side, then front bolt right side

Tighten the bolts on the first pass in sequence (1-8) to 3 N·m (27 lb in).
Tighten the bolts on the second pass in sequence (1-8) to 12 N·m (106 lb in).
Tighten the bolts on the final pass in sequence (1-8) to 15 N·m (11 lb ft).
