Depends on port and chamber design of a given engine. The exhaust ports are typically the hottest areas on the cylinder head. If we're talking VWs, the exhaust port areas are designed to be fan-cooled. Thermal barriers work, so I would think a reduction in heat absorption would occur. Significant reduction? I think you would have to try it and measure the results to see how effective it would be. I doubt if the results could be predicted.
