Over time, the OEM Duramax cast-aluminum cylinder heads exhibit shortcomings. Due to the disparate heat expansion rates between the cast-iron engine block and the cast-aluminum cylinder head, issues such as head gasket scrubbing and eventual blown head gaskets arise. Additionally, the aluminum cylinder heads are susceptible to warping, melting, or cracking, particularly in high-performance scenarios where elevated heat levels are introduced.
PPE’s new Cast Iron Cylinder Head is the ultimate upgrade to your Duramax engine and eliminates any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE Cylinder Head offers elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head’s lifespan significantly. PPE Cylinder Head also shares the same heat expansion rate as the stock cast-iron cylinder block – no more blown head gaskets.
Each head comes complete with upgraded valve train components. All valves are made of superior materials and fully nitridated. The tapered valve springs’ higher spring rate and lighter retainers/locators enable faster response during higher RPMs and eliminate valve float. Powder metal valve seats provide superior wear and heat resistance. The denser and stiffer material properties from the cast-iron construction also significantly reduce engine clatter.
Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, the PPE Cast Iron Cylinder Head is undoubtedly the best choice.
