The advantages of coating cylinder heads with Ceramic Thermal Barrier are:

The coating of combustion chambers in heads raises combustion temperatures and reduces overall head temperatures. This means more horsepower and less cooling is required. Aluminium heads are most often coated because they conduct heat away from the chamber faster thean cast iron heads.

For short periods of time combustion chamber temperatures can exceed 3000 degrees fahrenheit and exhaust gas temperatures 1600 degrees fahrenheit. Yet combustion chamber surfaces rarely exceed 600 degrees. This is due to the cyclical nature of combustion chamber activity. Combustion generated by heat, followed by a cooling air/fuel charge. Consequently, only a fraction of the heat generated is absorbed by the surfaces. This is not to say that a barrier is not desirable. Any decrease in part temperature reduces the burden on the cooling system and extends part life. In addition, if heat is not as rapidly lost then greater force is exerted against the piston for a longer period of time during the power stroke, creating more power.
