Hello folks,
I finally got around to replacing the cylinder head gasket on my '00 Metro this week so I'd like to share a succinct write-up of the procedure with you distinguished members ;)
1) Relieve the fuel system pressure.
2) Disconnect the negative battery cable.
3) Drain the cooling system.
4) Label and disconnect all necessary electrical connectors.
5) Label and disconnect all necessary vacuum, fuel, and water hoses.
6) Remove the intake manifold with the throttle body installed.
7) Remove the exhaust manifold.
8) Remove the timing belt and belt tensioner.
9) Remove the distributor cap, then mark the position of the rotor and the distributor housing with the cylinder head. Remove the distributor and the case from the cylinder head.
10) Remove the cylinder head cover.
11) Back off all valve lash adjusters until valves are closed if applicable.
12) Loosen and remove the cylinder head bolts in the reverse order of the tightening sequence.
13) Remove the cylinder head from the engine. Discard the cylinder head gasket.

**Shown here: Cylinder head tightening sequence**
--Installation--
1) Install the cylinder head gasket with the TOP indicator facing upward and to the crankshaft pulley side.
2) Install the cylinder head and eight cylinder head bolts. Lubricate the head bolts with engine oil prior to installation.
3) Tighten cylinder head bolts in the proper sequence to 54 ft. lbs. (73 Nm). Repeat tighten sequence several times before reaching specified torque figure.
4) Install rubber seals between the water pump and the cylinder head.
5) Install the cylinder head cover and secure with nuts and new seal washers. Tighten nuts to 44 inch lbs. (5 Nm).
6) Install timing belt and tensioner.
7) Install the distributor, aligning the matchmarks made during removal.
8) Install the intake manifold.
9) Install the exhaust manifold.
10) Connect all previously removed electrical connectors.
11) Connect all previously removed vacuum, fuel, and water hoses.
12) Adjust the accessory drive belt tension.
13) Adjust the accelerator cable play.
14) Refill the cooling system.
15) Connect the negative battery cable.
16) Start the engine and allow it to reach operating temperature.
17) Check for leaks.
18) Make any necessary adjustments.
