These Dart SHP Special High Performance cylinder heads are designed to provide an affordable option to those looking for the weight savings of aluminum heads for a performance street engine. They are manufactured from A356-T6 aluminum and are designed to work with most off-the-shelf components. These SHP cylinder 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 and designed to offer excellent flow and power without the need for CNC-machined porting. They feature optimized chambers for increased combustion efficiency and multi-angle intake seats. The cylinder heads' radiused exhaust seats dramatically increase their performance and the manganese bronze valve guides increase their life.
