Info

E-CNC oval port heads for big-block Chevy have a 24.5 degree x 4.4 degree intake valve angle, 15.5 degree x 4.2 degree 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 up to .700in. These E-CNC heads 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.

Notes

Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using. Heads have CNC intake ports, combustion chambers and exhaust ports, stock exhaust port locations, and the spark plug angles have been modified to produce a smooth flame front.
Some parts are not legal for use in California or other states with similar laws/regulations
