Cylinder Heads, Part II
We have an out-of-the-box Speed Pro 2.14-inch intake valve, (left); a Manley with a 30-degree back-cut above the original 45-degree face; and another Speed Pro, this time modified with a 30-degree face angle and back-cut at a shallower angle. It doesn’t get much slicker on the back of the valve than with our trick, modified 30-degree face valve. The undercut stem (arrow) on the Manley (center) valve had a minor effect on airflow. View Related Article
