1. Material: The cylinder head in Bare Engine is made of aluminum alloy, iron and other materials, and the surface of the cylinder head is electroplated to give the assembly good anti-corrosion ability.

2. Ventilation: There are vents on the cylinder head of Ford Mazda Engine, which can effectively reduce the pressure in the cylinder and keep the cylinder head working normally, thereby avoiding damage and failure caused by the collision of the cylinder and the piston.

3. Heat treatment: The cylinder head in Bare Engine is usually laser heat treated to increase the surface hardness and extend the service life of the assembly.

4. Sealing: The gaskets and washers in Bare Engine can effectively seal the cylinder head, prevent gasoline, lubricating oil, etc. from leaking from the cylinder body, and ensure the normal operation of the cylinder head.

5. Lubrication: The gaskets and washers of Ford Mazda Engine can effectively lubricate the cylinder head and prevent failures caused by wear of the cylinder head.

The characteristics of Bare Engine can effectively help the cylinder head to work normally, avoid damage and failure caused by the collision of the cylinder and the piston, and extend the service life of the cylinder head.
