Cylinder Head Assembly: Installation

NOTE:

Thoroughly clean all parts to be assembled.
Always use a new cylinder head and manifold gasket.
Always use a new cylinder head bolt.
The cylinder head gasket is a metal gasket. Take care not to bend it.
Rotate the crankshaft, set the No. 1 piston at TDC.

Install the cylinder head gasket (A) on the cylinder block.
NOTE: Be careful of the installation direction.
