Dart "SS" Cast Iron Small Block Chevy Heads

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.  

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.

 

“UnderCover Ported” Dart S/S Cylinder Head

The straight plug design Dart S/S heads are available with 1.94" or 2.02" valves. Looking for a lot of compression?  We can angle mill this head to 42 cc's!

Intake flow on stock SS heads 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 stock. With "UnderCover Porting" they improve to 175 to 185 cfm.
