8. Remove the valve rocker assembly.
9. Remove the camshaft.
10. Remove the cylinder head bolts in alphabetical sequence as shown in the figure.

NOTE: Leave bolts (a) and (c) engaged by three or four threads to prevent the cylinder head from falling.





11. While tapping the cylinder head with a plastic hammer, separate it from cylinder block.
12. Remove the bolts (a) and (c) to remove the cylinder head.





13. Remove the cylinder head gasket.

CAUTION: Be careful not to scratch the mating surface of cylinder head and cylinder block.

14. Similarly, remove the right side cylinder head.

Installation
1. Install the cylinder head and gaskets on cylinder block.

CAUTION:
^ Use new cylinder head gaskets.
^ Be careful not to scratch the mating surface of cylinder block and cylinder head.

2. Tighten the cylinder head bolts.
^ Apply a coat of engine oil to washers and bolt threads.
^ Tighten all bolts to 29 Nm (3.0 kgf-m, 21.4 ft. lbs.) in alphabetical sequence. Then tighten all bolts to 69 Nm (7.0 kgf-m, 50.9 ft. lbs.) in alphabetical sequence.
^ Back off all bolts by 1800 in reverse order of installation, and back them off again by 180°.
^ Tighten all bolts to 42 Nm (4.3 kgf-m, 31 ft. lbs.) in alphabetical sequence.
^ Tighten all bolts by 80° - 90° in alphabetical sequence.
^ Tighten all bolts by 40° - 45° in alphabetical sequence.

CAUTION: Tightening angle of the bolt must not exceed 45°.

^ Further tighten bolts (a) and (b) by 40° - 45°.

CAUTION: Total "re-tightening angle" of the step (6) and (7) must not exceed 90°.
