Trick Flow® High Port® 225 Cylinder Heads for Small Block Ford

Trick Flow® High Port® 225 cylinder heads are specifically designed for large cubic inch small block Ford engines as well as engines with high-boost superchargers or turbos, big shot nitrous oxide systems, and other mega-power combinations. They feature unique valve spacing, .750" raised exhaust runners, extra strong castings and thick decks for additional rigidity and gasket integrity, superior cooling characteristics, and most importantly, excellent airflow. Top-of-the-line CNC Competition Ported runners with a high resolution surface finish provide maximum airflow and power over the entire rpm range. The entry into the intake runner has been reshaped to help seal the area along the port roof and thicker port walls increase strength and provide additional material for porting. Plus, interlocking ductile iron seats are used to handle the stresses of high heat, high horsepower applications. Other features include fully CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending) and raised valve cover rails. Trick Flow® High Port® 225 cylinder heads are available fully assembled or as bare castings and sold individually.

FAST EZ-EFI 2.0 Multi-Port Retro-Fit Kits

FAST EZ-EFI 2.0 Multi-Port Retro-Fit kits allow owners of existing factory or aftermarket multi-port fuel injected applications and intake manifolds to experience the benefits of an EZ-EFI 2.0 system with no limit on horsepower—because the systems are based on each customer's supplied injectors. The next generation of the revolutionary self-tuning EZ-EFI has been upgraded with more features than ever before. Yet it maintains ease of use that doesn't require a laptop or tuning experience. As with the original EZ-EFI, simply hook up the system, answer the Setup Wizard questions on the hand-held, and EZ-EFI 2.0 tunes itself as you drive. The new high-quality wiring harness (with a sleek mesh-type loom) uses commonly available late model OEM sensors for accuracy and durability. The EZ-EFI 2.0 has an updated hand-held, as well, featuring the industry's first color touch screen. Self-powered through the ECU rather than requiring an outside power source, it shares the same mounting points as the Garmin Nuvi GPS—meaning there are nearly limitless mounting options (suction cup mount is included with all kits). Serving as the Setup Wizard initially, it then becomes an electronic gauge screen. The hand-held has various advanced features, including screen hide/sleep function, expanded diagnostics and data screens, plus intuitive navigation. Electronic fuel pressure measurement is standard on all kits—and all kits work with wet nitrous systems, providing built-in nitrous timing retard and special nitrous AFR targeting. EZ-Ignition features an EZ-Solution option, meaning that it is plug-and-play with FAST Dual-Sync distributors for electronic timing control, or can be used with an EFI distributor of your choice and a FAST crank trigger. Or the system can be used to control fuel only and be used with a standard carb-type distributor where timing is set manually. Experience the advantage of fuel injection without the headaches; order a FAST EZ-EFI 2.0 Multi-Port Retro-Fit kit.

Pacific Performance Engineering CNC-Ported LLY/LBZ/LMM Cast Iron Cylinder Heads

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).
