Edelbrock Victor 440 Cylinder-Head Test
Great attention to detail was paid to the combustion chambers of the ported Performer RPM heads during the first test. By tracing the shape of the head gasket onto the head, we were able to see exactly how much material we could remove to help unshroud the valves. All the sharp edges associated with the insertion of the valve seats were massaged, and any irregular contours in the chamber were smoothed to promote better flow. After all the material removal, the whole chamber was worked with a Scotch Brite pad. The dyno numbers told us all the extra work paid off. View Related Article
