Our Brand New Cummins OEM Cylinder Heads feature a genuine OEM casting equipped with brand-new Inconel intake and exhaust valves. Inconel provides exceptional strength and heat resistance under the extreme temperatures and heavy loads these engines are designed to endure.
​
While lower-cost aftermarket cylinder heads may offer an attractive upfront price, our heads combine a genuine Cummins OEM casting with premium Inconel valve components for customers who value proven fit, quality and long-term reliability. When you're investing in an ISX15 engine, the cylinder head isn't the place to compromise. All Cylinder Heads are sold NO-CORE.
