Dart SHP Special High Performance cylinder heads provide an affordable option for those who desire the weight savings of aluminum heads for a performance street engine. These units are manufactured from A356-T6 aluminum and are designed to work with most off-the-shelf components. SHP heads are available with your choice of 64cc or 72cc combustion chambers – and come in both 180cc and 200cc intake runner ports that are precision-cast to offer excellent flow and power without the need for CNC-machined porting. They feature optimized chambers for increased combustion efficiency, as well as multi-angle intake seats. The cylinder heads’ radiused exhaust seats dramatically increase their performance, and the manganese bronze valve guides increase their life.
