Thread Head bolt torque and sequence
Read the threads, but it states:
According to my manual the removal and the replacement sequence are different. Removal (looking from the cam sprockets )
headbolt 1-3-9-5-7 are on the left and 2-4-10-9-8 are on the right. Remove in that progression.
Instillation 9-5-1-3-7 are on the left and 10-6-2-4-8 are on the right tighten in that order.
Tighten to 25Nm or 18 ft/lb. and retighten the cyl hd blt 70 deg plus 70 deg plus 50 deg using the angular torque guage KM-470-B.
Hope this helps. Might help to make a sketch and label the 5 headbolts on each side.

Position the cylinder head on the cylinder block. Tighten the cylinder head bolts in 2 steps following the proper torque sequence. The first step is 37 ft. lbs. (50 Nm) and the second step is 68 ft. lbs. (92 Nm).
