    E-CNC 355 RECTANGLE PORT
    BIG-BLOCK CHEVY


    Edelbrock E-CNC rectangular port cylinder heads for big-block Chevy are an all new design that delivers maximum horsepower and torque in high performance street and light duty racing applications. To ensure consistency from port to port, the E-CNC heads are treated to a full CNC porting of the combustion chambers, intake and exhaust runners; this improves air-flow and overall performance potential These heads have a 24.5° x 4.4° intake valve angle, 15.5° x 4.2° exhaust valve angle, stock exhaust port locations, and the spark plug angles have been modified to produce a smooth flame front for increased fuel efficiency and maximum power. Two combustion chamber sizes are offered, 110cc and 118cc. These heads are equipped with high-quality valve springs for valve lifts of up to .700''.
