Description

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 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 Heads also share 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 valve springs feature higher spring rate, lighter retainers/locators, enabling faster response during higher RPMs. Alloy 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.

Requires the use of LBZ/LMM glow plugs on LLY engines
