Turner performance head has gasflowed inlet & exhaust ports = better volumetric efficiency = 8 - 10 BHP & claims of a fuel saving of approx. 2 mpg.
 
presumably modified & polished ports, so fuel/exhaust will flow in/ out faster, same for water ports will cool better, needed if yer creating more bang...
