Looking to coax every last bit of horsepower from your brand-new LS-series engine? Start with the Noonan LS Cylinder Head. Noonan Racing has been at the forefront of recent advancements in cylinder head design, and has brought together the latest in airflow-maximising technology to deliver a high-performance product custom-built for the LS Series.
The larger the valve, the greater the airflow. That simple proposition is at the heart of this cylinder head’s canted valve design. The canted angles are specially calibrated to accommodate high-diameter intake (2.250” with a 5/16” stem) and exhaust (1.610” with a 11/32” stem) valves that reduce shrouding risk and maximise airflow.
But speed is only half of the equation. You need a racing engine that can go the distance, delivering consistently top-end results all the way to the finish line. The LS Cylinder Head does just that. Instead of aiming to “minimise” leaks – a half-measure at best - we’ve eliminated water head leak risks from the equation altogether with an industry-leading weldless design, providing leak-proof performance. Combine that with a fully-billeted structure, heat-treated to T6, T&D roller rocker compatibility and an ultra-secure LSC head stud setup, and you get a cylinder head with world-beating durability and world-class performance.
