Edelbrock Victor 440 Cylinder-Head Test
The closed chamber of the Performer RPM and Victor heads provides dual quench areas that you can clearly see outlined on the piston. These pistons have 23 dyno pulls on them and still have clean areas clearly visible. Notice the clean, angled areas that mimic the spark-plug positions in the head. Make sure to put your pistons at zero deck height or higher to take full advantage of the antidetonation characteristics of the close quench design. View Related Article
