The bolt tightening sequence for all Chevy intake manifolds is the same, first you coat the bolts with some non-hardening sealer, align your gasket on the head and use some RTV silicone to seal the front and the rear of the manifold, finger tighten all of your bolts, then using a torque wrench starting from the center working your way to the front and back in a circular motion torque the bolts, the torque specs for the bolts is 30 ft-lbs but first torque to 20 ft-lbs and then 30 ft-lbs in the same pattern you used the first time you tightened them, this is the proper procedure
Yes.
Intake manifold at top of engine?
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
The intake manifold is bolted on the center of the engine between the 2 Valve covers.
