Re: 400 /07 / torque the head down
Tighten the cylinder head bolts and nuts diagonally and
evenly.
• The head bolt tightening must be performed in two stages, initial
and final tightening.
#Cylinder head bolt
Initial tightening:25 N·m (2.5 kgf-m, 18.0 lb-ft)
Final tightening: 41 N·m (4.1 kgf-m, 29.5 lb-ft)
#Cylinder head nut (M8): 25 N·m (2.5 kgf-m, 18.0 lb-ft)
Cylinder head nut (M6): 10 N·m (1.0 kgf-m, 7.0 lb-ft)
Cylinder nut : 10 N·m (1.0 kgf-m, 7.0 lb-ft)

Re: 400 /07 / torque the head down
The torque settings for the head bolts are in the Haynes manual. You must have missed them! Easily done.
Probably not ugly enough for the 'Ugly Bunch'!
