PPE's new Cast Iron Cylinder Head stands as the ultimate upgrade for your Duramax engine, eradicating head gasket and cracking concerns. Crafted from high-quality alloyed gray iron, it offers elevated fatigue strength, heat, and creep resistance, significantly prolonging its lifespan. Sharing the same heat expansion rate as the stock cast-iron cylinder block eliminates blown head gaskets. The head includes upgraded valve train components with fully nitridated valves, tapered valve springs for rapid response, and powder metal valve seats for superior wear resistance. The denser cast-iron material also reduces engine clatter, making it the top choice for durability and reliability.
