Hi,

I can help you with this.

Just to be sure we are on the same page and you get the correct information, this is a real OZ with the 2.0 non-turbo 4G95 engine.

You will need to have NEW cylinder head bolts, these are torque to yield bolts that can not be reused.
Tighten the bolts in the order shown in the following diagram:
graphic
You will tighten one pass in the order shown in the diagram up to 54 ft/lbs, then fully loosen the bolts.
Re-tighten one pass in the same order up to 15 ft/lbs
Paint mark all head bolts
Turn one pass in the same order 90 degrees
Turn one pass in the same order an additional 90 degress.
Complete.
