Edelbrock Performer RPM Chrysler Gen III HEMI cylinder heads are bolt-on performance upgrades for Gen III HEMI engines. They are designed to fit with the stock intake manifold, exhaust manifold, valve cover, rockers, spark plugs, and accessories, as well as Hellcat components. The cylinder heads have been machined to be used on either the driver or passenger side of the block. They are cast from A356 aluminum and are heat-treated to T6 specifications. Edelbrock Performer RPM Chrysler Gen III HEMI cylinder heads feature fully CNC-machined combustion chambers, along with CNC-profiled bowls and port entries/exits for improved airflow. They also feature more material in the deck and reinforced combustion chambers for increased cylinder pressures. The rocker bosses have been reinforced for improved stability and strength, and extra material has been added around the intake and exhaust ports to allow for porting in racing applications. Both the intake and exhaust port flanges have remained in the factory location for use with OEM components. The intake and exhaust valves have been tipped away from the bore wall to unshroud the larger valves, while maintaining factory geometry. The seat diameters have also been increased for improved heat transfer and durability over stock.

S&S Cycle Performance cylinder heads are replacements for Big Twin engines. Designed to be compatible with a stock-style flat topped piston, their larger than stock intake and exhaust valves provide plenty of air while maintaining port velocity for good low and midrange response, while the S&S high-lift valve springs allow the installation of cams with up to .585 in. lift. S&S Cycle Performance cylinder heads are compatible with stock intake manifolds, exhaust systems, and temperature sensors for EFI-equipped models. Select low or standard compression heads with a natural aluminum or wrinkle black powdercoat finish for your Big Twin engine. * Low compression sets have a slightly larger 82cc combustion chamber, making them ideal for larger displacement applications, producing a manageable compression ratio. These heads are original equipment on S&S V96 and V80 engines. * Standard compression sets have a 76cc combustion chamber that gives a slight increase in compression for great results with most performance cams.

Valve guides on Harley-Davidson® motorcycles are essential for proper valve operation. S&S Cycle valve guides are designed to provide optimal engine performance by accurately aligning the valves, minimizing friction, dissipating heat generated during combustion, and preventing valve stem wear, ultimately leading to better power delivery, fuel efficiency, and engine longevity. The valve guides are typically made from materials like bronze or cast iron, each with its own wear characteristics and heat transfer properties and help to maintain the integrity of the combustion process by guiding the valves to open and close correctly. Select the S&S Cycle valve guides recommended for your bike's application needs. Features and benefits: * Proper valve alignment—valve guides precisely position the valve stems, allowing them to open and close correctly at the right time, crucial for efficient air intake and exhaust gas expulsion * Reduced friction—the smooth surface of a good valve guide minimizes friction between the valve stem and the guide, reducing wear and heat generation * Heat dissipation—the material of the valve guide is designed to conduct heat away from the valve stem, preventing excessive overheating which can damage the valve * Valve stem protection—by guiding the valve stem accurately, the valve guide prevents the valve from contacting other engine components, reducing potential damage * Improved engine performance—with proper valve operation facilitated by the guides, the engine can achieve optimal power and efficiency * Extended engine life—well-maintained valve guides contribute to a longer engine lifespan by minimizing wear on critical components like the valve stems and valve seats Important considerations regarding valve guides: * Material selection—valve guides are typically made from materials like bronze or cast iron, each with its own wear characteristics and heat transfer properties * Clearance—maintaining the correct clearance between the valve stem and the guide is vital to prevent excessive friction and wear * Regular maintenance—periodic inspections and replacements of valve guides are necessary, especially when experiencing symptoms like decreased engine power, excessive oil consumption, or unusual engine noises
