About Cylinder Head Services
Cylinder heads can help generate power but can also help lose power. It’s all in the details. Our Serdi 100 machine and Serdi HP cutters combine to give you the best possible valve seat job available. The cutter contains 11 individual angles across a smooth radius. And with valve angles ranging between 30 and 55 degrees, we can help you pick the best for your heads. Custom hand porting is also available and we also have connections to the best CNC porting shops around.
