PPE CYLINDER HEAD (ONE) CAST IRON 2011-2016 6.6L LML DURAMAX

PPE's new Cast Iron Cylinder Head stands as the ultimate upgrade for your Duramax engine, addressing head gasket and cracking concerns. Crafted from high-quality alloyed gray iron, it exhibits elevated fatigue strength, heat, and creep resistance, significantly extending the cylinder head's lifespan. Sharing the same heat expansion rate as the stock cast-iron cylinder block eradicates blown head gaskets. The head includes upgraded valve train components with fully nitrided valves and tapered valve springs for rapid response. Powder metal valve seats offer superior wear and heat resistance. The denser cast-iron construction also reduces engine clatter, making it the top choice for reliability and longevity.

Features:

• Specially alloyed gray cast iron liquid-cooled cylinder head
• Elevated strength in high temperatures and creep resistance
• Same heat expansion rate as OEM iron block, resolving head gasket scrubbing
• Cast-in fuel injector cups eliminate leaks from original cup seals
• Higher fatigue strength and heat resistance extend cylinder head lifespan
• Premium 21-4N, Stellite-reinforced exhaust valves; chrome-silicon alloy intake valves
• Fully nitrided valves for increased abrasion resistance
• High-strength Chromoly steel CNC-machined spring retainers and locators
• Upgraded tapered valve springs for faster response, no valve float at high RPMs
• Powdered metal valve seats for superior wear and heat resistance
• Reduced diesel engine clatter compared to factory aluminum heads
• Increased thermal efficiency compared to aluminum alternatives
