Head Bolt Torque: For a 2012 Chevrolet Spark with a Daewoo 1.0 Liter DOHC engine, the cylinder head installation and head bolt torque settings are 22 N-m + 82 degrees (16 lb ft + 82 degrees) you say the engine size is .8 liters? Can you please confirm?

Yes, it is a .8-liter (800cc) engine. I also need the flywheel, big end and main bearing settings.

Okay I had to confirm,
Flywheel Bolts: The torque specification for the flywheel bolts is usually around 85 to 95 Nm (Newton meters). However, it's essential to apply a thread-locking compound to these bolts before installation.
Crankshaft Main Bearings:
The crankshaft main bearing cap bolts are typically torqued in two stages. The first stage is around 15 to 20 Nm, and the second stage requires an additional angle turn, often 60 to 70 degrees.
For the crankshaft main bearing cap side bolts, if equipped, the torque is usually lower, around 10 to 15 Nm.
Connecting Rod Bearings:
The connecting rod cap bolts are also torqued in two stages. Initially, they are tightened to approximately 15 to 25 Nm, followed by an additional angle turn, typically around 60 to 65 degrees.
