SOURCE: Torque Spec for '99 Chevy C1500 5.7L engine lower intake manifold

On 5.7L engines, install the bolts and torque in sequence as follows:

1. Step 1: 71 inch lbs. (8 Nm).
2. Step 2: 106 inch lbs. (12 Nm).
3. Step 3: 11 ft. lbs. (15 Nm).

SOURCE: how do u no if u have a bad head gasket or blown

Easiest way to test the intake gasket is to get a can of starting fluid and spray it around the intake area while the vehicle is running. Be careful, starting fluid is extremely flammable! If you notice an accelleration, or de-celleration while spraying the starting fluid, you can pinpoint the leak from there.

If you have a bad head gasket, you will see a white mucky substance on your oil dipstick.

I hope this helps you, and I wish you luck on your repair.

SOURCE: What is the torque spes

For 2004 Chevrolet Truck Silverado 2500HD 4WD 6.0L SFI 8cyl, the intake manifold, throttle body, fuel injection rail, and fuel injectors may be removed as an assembly. If not servicing the individual components, remove the manifold as a complete assembly.

Intake manifold bolts. Tighten intake manifold bolts first pass in sequence to 44 inch lbs. (5 Nm). Tighten intake manifold bolts final pass in sequence to 89 inch lbs. (10 Nm).
