Rocker arm installation
I'm following the instructions on ls1howto.com but they're meant for
a C5.
It says to torque em all to 22 ft/lb crank motor 180 degrees and
check the torque again.
I'm using all stock parts. Is this right, there are some pretty extravagant rocker dyi write ups that tell you to pre load, tdc etc etc, am I doing this wrong?

In this position, cylinder number 1 rocker arms will be off lobe lift, and the crankshaft sprocket key will be at the 1:30 position. The camshaft and crankshaft sprocket alignment marks (1, 2) will be in the 12 o'clock position. If viewing from the rear of the engine, the additional crankshaft pilot hole, non-threaded, will be in the 10:30 position.
The engine firing order is 1, 8, 7, 2, 6, 5, 4, 3.
Cylinders 1, 3, 5 and 7 are left bank.
Cylinders 2, 4, 6, and 8 are right bank.
Caution: Refer to Fastener Caution in the Preface section.
With the engine in the number 1 firing position, tighten the following valve rocker arm bolts:
7.1. Tighten the exhaust valve rocker arm bolts 1, 2, 7, and 8 to 30 N·m (22 lb ft).
7.2. Tighten the intake valve rocker arm bolts 1, 3, 4, and 5 to 30 N·m (22 lb ft).
Rotate the crankshaft 360 degrees.
Tighten the following valve rocker arm bolts:
9.1. Tighten the exhaust valve rocker arm bolts 3, 4, 5, and 6 to 30 N·m (22 lb ft).
9.2. Tighten the intake valve rocker arm bolts 2, 6, 7, and 8 to 30 N·m (22 lb ft).

over torque. Remember these are aluminum heads.
