Have not had it apart but from what I see, there are two allens and 8 bolts (cap screws). Allen on right when you are facing it is bolt 1, the four behind it are 3,7,9,5. Allen on left is bolt 2 the four behind it are 6,10,8,4. (Draw it out on paper) Those numbers are your torque sequence. You will be STARTING WITH bolts # 3-10. Bolts 1&2 get done very last. Lubricate the bolts (cap screws) and secure head to crankcase to 18 ft lbs in correct sequence, then loosen all the bolts and re-tighten to 18ft lbs again in the correct sequence. After you have done this, following the same torque sequence tighten each one an additional 175-185 degrees, or appx. 1/2 turn. Do not use a torque wrench for the final tightening. Tighten allen screws 1&2 to 8.7 ft lbs. From the manual.
