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.

Nice Head for the money

Summit RacingSummit Racing Verified Purchase

Dart suggest you use their adjustable guide plates, but yet on the assembled heads they send non-adjustable. and also the push rods are very close in the push rod holes. Pros are I had my heads ported and they flow over 300 cfm at .600 lift and the shop that did them said they were really nice to work with

poor casting

Dart has a problem with there castings, stay away from the SHP series.Rocker arm and push rod alinegment are way off. pushrods rub against the intake runner.
