Different heat expansion rates between cast-iron engine block and cast-aluminum cylinder head cause head gasket scrubbing and eventually blown head gaskets. Made for performance, these heads can handle the heat without warping, melting, or cracking.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eCast from high-quality alloyed gray iron, the PPE Cylinder Head offers elevated fatigue strength, and 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. PPE LML Cylinder Heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDiscover improved valve train components included in each head.
