Product Name: PPE Cylinder Head (One) Cast Iron LLY/LBZ/LMM Manufacturer: PPE Manufacturer Part #: 110100103 Thoroughbred Diesel Part #: PPE110100103 Fitment Notes: This part fits 2004.5-2010 GM 6.6L Duramax LLY/LBZ/LMM, it will fit both sides of the motor.
The OEM Duramax cast-aluminum cylinder heads fall short over time - the different heat expansion rates between cast-iron engine block and cast-aluminum cylinder head cause head gasket scrubbing, and eventually blown head gaskets. The aluminum cylinder heads are also prone to warping, melting, and/or cracking in high-performance applications where excessive heat is 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 grey 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.
