March Performance Ultra Series Chevy Small Block serpentine systems bolt to the front of 1969 or later small block Chevy heads. Precision CNC-machined from solid billet 6061-T6 aluminum to fit perfectly and handle high torque and vibration, these bracket kits come complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. All necessary hardware included. Powdercoated to eliminate polishing in those hard to reach places. Matching serpentine pulleys are precision CNC-machined from 6061-T6 aluminum. This is the same material March uses for NASCAR pulleys! These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. March hard coats the high-wear areas on the high-water flow ratio pulleys! The street rod ratio increase water flow and fan speed. This helps at critical low speed driving.

PPE's CNC-ported LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine to eliminate any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE cylinder heads offer elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head's lifespan significantly. The cylinder heads also share the same heat expansion rate as the stock cast-iron cylinder block—no more blown head gaskets! PPE's CNC-porting process improves airflow, enhancing power, fuel efficiency, and throttle response while reducing engine stress and turbo lag. By smoothing the ports and maintaining wall thickness, these heads provide increased horsepower and torque without sacrificing reliability. Tailored to each specific head, the CNC machining compensates for casting variations, ensuring consistent and optimized airflow dynamics. 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).
