The Dart Small Block Chevy Iron Eagle S/S Cylinder Heads are the perfect way to squeeze a little bit more performance out of your street engine. Dart engineers these heads from premium, high-density cast iron with extra-thick decks for durability and power potential. These heads feature precision-cast 165cc intake ports and heart-shaped combustion chambers that are designed to produce great airflow without expensive or time-consuming porting. Dart utilizes screw-in rocker studs that won't pull out, even under heavy use, and the machined valve cover rails eliminate possible oil leaks. All you have to do is choose which combination of combustion chamber volume and valve size will best complement your engine. Whether you want fully assembled, bolt-on heads or bare, ready-to-build castings; Dart Iron Eagle S/S cylinder heads produce great throttle response and gains in low-to-midrange torque, just where you need it, for your street warrior!
