What is the torque setting for the bolts thanks

1. First, tighten all the bolts to 25 Nm (18 lb-ft).
2. Tighten all the bolts to 50 Nm (37 lb-ft) in sequence, starting from the center and working outward.
3. Tighten all the bolts to 70 Nm (52 lb-ft) in sequence again, starting from the center and working outward.
4. Finally, tighten all the bolts an additional 90 degrees in sequence again.

Please note that it's important to follow the correct torque sequence and to use a torque wrench to ensure that the bolts are tightened to the correct specifications. It's also recommended to replace the head bolts with new ones to ensure proper torque and head gasket sealing.

Cylinder head bolt torque sequence-3.4L engine

Cylinder head by aligning it with the dowel pins

New cylinder head bolts coated with a sealant (such as GM 1052080). Torque the bolts in the proper sequence (1-8) to 37 ft. lbs. (50 Nm). Using a torque angle meter turn the bolts 90 degrees in the proper sequence.

Left side exhaust manifold. Torque the bolts to 12 ft. lbs. (16 Nm).

Spark plugs. Torque the plugs 11 ft. lbs. (15 Nm).

Right side rear cylinder head:
