Cutting Valve Seat Angles at Daniel Isaac blog

Cutting Valve Seat Angles. The valve seat cutters feature multiple valve angles that are proven to significantly improve airflow and power over a single angle or. The valve seat cutter is designed to cut a specific angle into the valve seat, ensuring the valve can seal against the cylinder head with the correct angle and two angles or more with a perfectly flat surface for valve contact. The diagram below shows the three angles: Valve seat runout tolerances will vary based on stem size, head diameter, seating angles, etc. A single 45 degree angle cut on the valves and seats won’t provide the same airflow, throttle response and power as a three angle. Generally 60°, this is the bottom angle which transitions airflow. Sometimes this is an option, and other times, the number of angles is decided for you. In addition to the degree and width of a seat angle, you also have options in terms of how many angles get cut during a valve job. These tolerances are often called out in the. After the valves have been lapped, a backcut is placed on the.
