head bolts,

Install the 18 cylinder head bolts.
Lightly lubricate the cylinder head bolt threads and flanges with clean engine oil.
Tighten the bolts in the sequence shown in three stages.
Stage 1: Using the first sequence, tighten the bolts to 88 Nm (65 lb-ft).
Stage 2: Using the first sequence, tighten the bolts to 115 Nm (85 lb-ft).
Stage 3: Using the second sequence, tighten the bolts to 129 Nm (95 lb-ft).

the Head bolts



First sequence"

13 5 4 12
17 9 1 8 16
18 10 2 7 15
14 6 3 11


second

15 16 17 18
10 11 12 13 14

they are numbered by tightening sequence. 120 inch lbs is 10 foot lbs. I would get an inch lbs wrench I use em for smaller measurements just to be safe.

I couldn't read the sequence in the above image, could just be my eyes, but here is a larger one. I hope this helps.
The order is the same but the specs are a little different in this image. I have seen the specs from driximus in more than one place I would use them and not the ones in this image.
