The 2014 Chevy Spark intake manifold torque sequence and torque specs depend on the engine type. Here are the torque specs and sequence for each engine type:
1.0L Engine:

• Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
• Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
• Step 3: Tighten the bolts to 18 lb-ft (25 Nm).

Torque sequence: 8 4 1 5 9 7 3 2 6 10
1.2L Engine:

• Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
• Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
• Step 3: Tighten the bolts to 18 lb-ft (25 Nm).

Torque sequence: 8 4 1 5 9 7 3 2 6 10
It's important to follow the torque sequence and torque specs carefully to ensure that the intake manifold is properly secured and sealed. Over-tightening or under-tightening the bolts can cause leaks or damage to the engine.

2001 GMC Truck Sierra 1500 4WD 5.3L SFI 8cyl

The Lug Nut Tightening Torque 140 Foot pounds (Final torque).

starting at the middle bolt and go directly across then criss cross the pattern like you would tightening wheel nuts, towards the outside(end) bolts. if this is a plastic upper intake the torque should be around 15ft lbs if its metal around 25ft lbs.

According to Haynes Manual, 2005 Nissan Altima, using BRAND NEW cylinder head bolts:

1 - Tighten in sequence (as pictured) to 37 ft-lbs.
2 - Tighten an additional 60 degrees.
3 - Loosen all bolts completely.
4 - Tighten in sequence 26 - 32 ft-lbs.
5 - Tighten in sequence an additonal 75 degrees.
6 - Tighten in sequence an additional 75 degrees.

Fig.: Cylinder head bolt torque sequence-2.2L engine

Apply a coating of 1052080 or equivalent sealer to the cylinder head bolt threads. Install the cylinder head bolts (within 15 minutes of sealer application), then tighten them in the proper sequence first to a torque of 46 ft. lbs. (63 Nm) for long bolts or to 43 ft. lbs. (58 Nm) for short bolts and then tighten all bolts an additional 90 degree turn using a torque angle meter.

Hope this helps (remember to rate this answer).

the rocker arm torque specs for the la1 gm 3400 sfi v6 is 168in lbs or 14ft lbs and 30degrees past that hope that helps you it came straight from my local dealer!
