Good afternoon,

I attached the sequence and the torque spec for installing the head.

Make sure you use only new bolts. These are TTY or torque to yield bolts.

Here is the left and right side sequence. Tighten the cylinder head bolts. Bolt 10 and 9 are different / shorter and have a different spec when tightening

1. Tighten the M11 cylinder head bolts?1-10 a first pass in sequence to 22?Lb?Ft.

2. Tighten the M11 cylinder head bolts?1-10 a second pass in sequence to 90? Degrees using J 45059 angle meter.

3. Tighten the M11 cylinder head bolts?1-10 a final pass to 70? Degrees using J 45059 angle meter.

4. Tighten the M8 cylinder head bolts?11-15 to 22?Lb?Ft. Begin with the center bolt?11 and alternating side-to-side, work outward tightening all of the bolts.

This video will show you how to use a torque wrench in case you need it.

Hello,

Here are diagrams showing you how the cylinder head is done with the torque specs BELOW. This video shows how to use a torque wrench. FOr this engine you will also need a torque angle meter to get eh correct degree count when torquing

See pics all cylinder head bolts must be new as they are torque to yield bolts. Must also be done in sequence.
