From raw casting to race-ready cylinder heads turning your goals into a reality.

Today’s shipment shows where the process begins. The assembled head shows what comes next after precision machining, finishing, and careful inspection here at Jon Kaase Racing Engines.

The raw casting provides the basic shape, including the intake and exhaust passages and internal water jackets. Our in-house 5-axis CNC machines the critical surfaces and features—shaping combustion chambers, machining mounting surfaces, and preparing locations for valve seats, guides, and hardware.

From there, the seats and guides are installed and finish-machined for proper valve fit and sealing. After cleaning and inspection, the valves, springs, retainers, and remaining components bring the head to its assembled form.

There’s a lot of craftsmanship between these two photos—and every step matters when it’s time to make horsepower.

We will NEVER FORGET 911. 🇺🇸
The lives lost, the families destroyed, and the aftermath that continues to this day. We also won’t forget the heroism of those who chose to run toward the danger while everyone else ran away.
Our Police, firefighters, and everyday citizens put their lives at risk—and many paid the ultimate price so that others could go on.
Please say a prayer for them and their families today as we all try to be better moving forward. 🙏🕯️
