limited info generic answer if looking for all specs then buy a repair manual multi sites online can download or hardcopy -

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.

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.

22 - 24 ft. lbs. for the rod caps and....
Cylinder Head Tightening Torque and Sequence.

Tighten cylinder head bolts in order shown.
Tightening torque: 36.1 ft. lbs. (49 Nm, 5 kg-m)

Loosen bolts in reverse of order shown.

Retighten cylinder head bolts in order shown.
Tightening torque: 18 ft. lbs. (25 Nm, 2.5 kg-m)

Mark cylinder head bolts for rotational reference.
Rotate cylinder head bolts 90°(1/4 Turn) in order shown.

CAUTION:

• Do not reuse the old cylinder head bolts.

On the V8, tighten the bolts, in the sequence illustrated, to 100 ft. lbs. When all bolts have been tightened to this figure, begin the tightening sequence again, and torque all bolts to 130 ft. lbs.

On V6's, tighten all head bolts in sequence to the following torques:
* All except bolts 5, 6, 11, 12, 13 and 14 - 100 ft. lbs.(19-135.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 41 ft. lbs. (19-55.5 Nm)
* All bolts except 5, 6, 11, 12, 13, and 14 - 142 ft. lbs. (19-192.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 59 ft. lbs. (19-80 Nm)



Hope this help (remember comment and rated this).

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

1. 20 Nm (15 lb-ft).

1. 40 Nm (30 lb-ft).

1. 50 Nm (37 lb-ft)

Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:

• Tighten to 40-50 Nm (30-37 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.

Short Bolts:

• Tighten to 20-30 Nm (15-22 lb-ft).
• Rotate an additional 175-185 degrees.
• Go to next bolt in sequence.
