1 Tighten cylinder head bolts in the specified sequence diagonally across (1 to 4) in stages to the specified torque and tightening angle.

If a bolt has been excessively tightened, unscrew all the 4 bolts of the cylinder head in question and inspect the shank length of the bolts. Bolts which have stretched excessively must be replaced and then repeat the step again.
