Description
Duramax Ported Cast Iron Cylinder Head - 2001-2004 GM 6.6L (One Head) LB7 The OEM Duramax cast-aluminum cylinder heads fall short over time – the differing heat expansion rates between the 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 ported LB7 Cast Iron Cylinder Head is the ultimate upgrade for your Duramax engine, eliminating any concerns about head gaskets or cracking. Cast from high-quality alloyed gray iron, the PPE Cylinder Head offers superior fatigue strength, heat resistance, and creep resistance, significantly prolonging its lifespan. The cast-iron material also shares the same heat expansion rate as the stock engine block, eliminating blown head gas
