Dart "SS" Cast Iron Small Block Chevy Heads
Dart Iron Eagle S/S heads produce great throttle response and low to mid-range torque for street performance and Street Stock type circle track applications. The precision cast ports and combustion chambers produce good air flow. Features include a thick deck surface for increased durability, machined valve cover area, hardened exhaust seats, efficient combustion chamber design & machined for screw-in studs.
Intake air flow on a stock SS head is in the 230 - 234 cfm range. This can be improved a bit with a valve job and some chamber work to achieve air flow in the 240 cfm area.
The exhaust ports will flow close to 140 cfm in stock form. With our “UnderCover Porting" the exhaust flow will improve to 175 to 180 cfm.
The Dart S/S head is one of the best performing heads for limited applications like Pro Stock, Super Stock, Limited Late Models and other such classes throughout the country. It is an excellent alternative to the Chevy “double hump” heads and it makes more power.
