| | Hemi Cast Iron Cylinder Heads are designed for more power. Stiffer and stronger than original, increased material permits porting for improved airflow. Features the same outward
appearance as the original 1966 - 1971 heads, except for the shape
of the alternator boss. All components attach the same as
original (intake and exhaust valves, valve guides, seats, rocker gear, etc.). Features 170 cc combustion chamber and 2.25" intake
and 1.94" exhaust valve machining.
