Okay, this must be done correctly or the head bolts may break or strip out so please follow these instructions.
Tighten the bolts in sequence using the following steps and torque values :
Step 1: Tighten bolts 1-8, 27 Nm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nm (20 ft. lbs.), by repeating step 1
without loosening the bolts. Tighten bolts 9 thru 12 to 14 Nm (10 ft. lbs.).
Step 3: Tighten bolts 1-8, 90 °.
Step 4: Tighten bolts 1-8, 90 °, again. Tighten bolts 9-12, 26 Nm (19 ft. lbs.)
Here is the tightening sequence as well. Check out the images (below). Let me know if you need anything else.
