The cylinder head is a one piece, cross flow design with two valves per cylinder. The head has integrally cast valve
guides and hardened valve seat surfaces which can be repaired in a machine shop using the appropriate service parts.
The cylinder head has a cast intake manifold, fuel filter head, thermostat housing and an internal water bypass.
The injectors are mounted in the head for direct injection into the cylinders. Fuel filter head is remote for engines
with inline fuel injection pump.
Separate pedestals for each cylinder are used to support and route oil to the rocker levers.
The cylinder head gasket is a laminated design with print-o-seal on both sides around the water holes. An embossment in the gasket seals the cylinder bores. As discussed in the Cooling System, the gasket also provides orifices to control coolant flow.
