Description
Duramax Cast Iron Cylinder Head 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 trai
