Final answer:
The cylinder head is bolted to the engine block, where it houses essential components like valves and forms part of the combustion chamber.
Step-by-step explanation:
The cylinder head is a crucial component of an internal combustion engine and it is bolted to the engine's block. This part serves as a housing for components such as the intake and exhaust valves, springs, and combustion chamber. It is positioned above the cylinders on top of the cylinder block. The cylinder head is sealed to the block with a head gasket and is fastened with cylinder head bolts, which must be tightened to a specific torque specification to ensure a proper seal and prevent engine damage.
