    E-CNC 325 OVAL PORT
    BIG BLOCK CHEVY


    E-CNC 325 oval port heads for big block Chevy have a 24.5° x 4.4° intake valve angle, 15.5° x 4.2° exhaust valve angle, stock exhaust port locations and spark plug angles that have been modified to produce a smooth flame front for increased fuel efficiency and maximum power.

    These heads are equipped with high-quality valve springs for valve lifts of up to .700'' and are also treated to a full CNC porting of the combustion chambers as well as the intake and exhaust runners. This improves air-flow and overall performance potential.
