Once you see Trick Flow® PowerPort® 240 heads for big block Mopar in action, you'll agree they are the only aftermarket aluminum heads worth using on your engine! What makes PowerPort® 240 heads so great? For starters, they're made from premium grade A356-T61 aluminum. That's important because it weighs a lot less than cast iron and is very strong. Trick Flow® engineers then fixed the shortcomings of the factory head design by relocating the oil holes for the rocker shafts and optimizing the shape of the runners to increase flow velocity and add much needed strength to the shaft bosses. Fully profiled combustion chambers and CNC Street Ported runners guarantee proper dimensional accuracy and balanced flow from runner-to-runner for maximum power potential. Additional advantages of PowerPort® 240 heads over stock heads include clearance for 3/8 in. pushrods, ductile iron valve seats, bronze alloy valve guides, and multi-angle valve seat machining on precision Serdi® equipment. Assembled cylinder heads come with premium 11/32 in. stainless steel valves, Trick Flow® by PAC Racing valve springs, chromoly and titanium retainer options, and 7 or 10 degree steel valve stem locks. Since swapping cylinder heads can be a costly and time-consuming process, Trick Flow® designed the PowerPort® 240 heads to accomodate all factory-style big block Mopar pistons. They are also manufactured to accept aftermarket roller rocker arms, intake manifolds, and headers. They are available fully assembled or as bare castings. Sold individually.

OEM Duramax cast aluminum cylinder heads fall short over time; the different heat expansion crates between cast iron engine block and cast aluminum cylinder head cause head gasket scrubbing, and eventually blown head gaskets. Aluminum cylinder heads are also prone to warping, melting, and/or cracking in high performance applications where excessive heat is introduced. Pacific Performance Engineering LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine and eliminate any head gasket or cracking concerns. Cast from high-quality alloyed grey iron, PPE LLY/LBZ/LMM cylinder heads offer elevated fatigue strength and heat and creep resistance, which prolongs the cylinder head's lifespan significantly. They also share the same heat expansion rate as the stock cast iron cylinder block, so no more blown head gaskets. These cylinder heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue. Each head comes complete with brand new springs, spring retainers, spring locators, valves, valve seals, valve keepers, valve seats, valve guides, rocker arm dowels, and freeze plugs. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, the Pacific Performance Engineering LLY/LBZ/LMM cast iron cylinder head is undoubtedly the best choice. Component features and benefits: * Premium 21-4N, Stellite-reinforced exhaust valves, and chrome-silicon alloy intake valves * All valves are fully nitridated with increased abrasion resistance * High-strength, CNC-machined chromoly steel spring retainers and spring locators * Upgraded tapered valve springs provide faster response and eliminate valve float at high rpms * Powdered metal valve seats offer superior wear and heat resistance * Significantly reduced diesel engine clatter compared to the factory aluminum cylinder heads * Increased thermal efficiency compared to aluminum heads * 3-Year Unlimited Mileage Warranty
