Pacific Performance Engineering LLY/LBZ/LMM Cast Iron Cylinder Heads
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

Pacific Performance Engineering MicroPure Extreme-Performance Oil Filters
Pacific Performance Engineering MicroPure Extreme-Performance engine oil filters offer 2.5 times the filtration area of a conventional oil filter, providing the performance your engine oil needs to stay cleaner and for longer periods. Specially engineered synthetic filtration media achieves superior filtration to trap particles down to 5 microns, while a high-powered magnet secured at the bottom of the filter catches metal debris, preventing it from clogging the filter media and prolongs oil life. MicroPure's bypass valve is 10 psi stiffer than the OEM bypass valve and reduces the chance of dirty oil bypassing, and a heat-resistant silicone anti-drain-back valve retains the oil in the filter after the engine is turned off. With increased filtration area, four times finer media, and prolonged filter life, the PPE MicroPure Extreme-Performance filter is the ultimate choice for your engine. Additional features and notes: * 900 sq. in. of premium composite filtration media, a 150 percent increase over stock * Perforated metal core and spiral-wrapped adhesive secures filter media * 3/16 in.-16 UNF threaded baseplate with 47 percent larger passages * Direct replacement for the stock oil filter * High-power internal Neodymium magnet * 50 percent thicker base plate * Withstand 450 psi maximum burst pressure * TorqueStop feature to ensure a tight seal * Reinforced silicone anti-drain-back valve ensures a unidirectional flow

Pacific Performance Engineering Premium High-Efficiency Spin-On Transmission Fluid Filters
Pacific Performance Engineering recognized the need for better filtration for the hard-working Allison 1000 and 2000 transmissions, so they developed the Premium high-efficiency spin-on transmission fluid filters. These superior filters are designed to address the limitations of the standard "shorty filter". Inside the PPE double-deep spin-on filter is 2.72 times more filter media surface area. This increased surface area allows improved fluid flow and filtering. The double-deep filter traps particles down to 15 microns—that is half the size of what the standard spin-on filter catches, which helps to create a cleaner flow of oil to vital internal components, resulting in smooth, more responsive shifts. Do more to protect your Allison transmission and realize better performance. Don't come up short. Spin-on PPE's high-efficiency transmission fluid filters!

Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, cast iron cylinder heads from Pacific Performance Engineering are undoubtedly the best choice. Product features: * Specially alloyed gray cast iron liquid-cooled cylinder head * 5-Axis CNC-ported intake and exhaust ports for smooth, unrestricted airflow * Increased thermal efficiency compared to aluminum heads * Reduced noise and vibration, better ride * Eliminates head gasket scrubbing issue (blown head gasket) * Higher fatigue strength and heat resistance * Premium 21-4N, Stellite-reinforced exhaust valves * Fully nitridated valves, better abrasion resistance * Ready to install—comes with all valvetrain components, rocker arm dowels, and freeze plugs * Requires the use of LBZ/LMM glow plugs on LLY engines (sold separately) Important Notes: The valve seats of the PPE heavy cast iron cylinder heads are installed with an interference that maximizes the durability and lifespan of the cylinder heads. Such interference might not be optimal for extreme-performance applications where a significant amount of heat is created. For those applications, PPE suggests that the exhaust valve seats be replaced with higher interference (+0.006 in. to +0.008 in.) oversized exhaust valve seats (Nominal size 34mm).
