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.

High performance just got a lot easier and more affordable with S&S Cycle's CNC-ported B2 cylinder heads. In the past, S&S's B2 Special Application heads, that were used on the now legendary Tribute 145 engines, were often hailed as the best choice for very large displacement V-Twin engines. Now S&S Cycle offers CNC-ported B2 cylinder heads that are even better—providing added convenience, economy, and performance at the same time. Convenient, because they now fit 2008-later bagger front motor mounts and the new two bolt exhaust mounting flange is a lot easier to work with. Economical, because riders can use stock exhaust pipes, or existing 2 in. header systems. The increase in performance comes from increased flow of CNC-ported intake and exhaust ports. Heads features stock bolt pattern and require special pistons, intake manifold flanges, and pushrod length for installation. Features and benefits: * 106cc combustion chambers * Oval intake ports bolt up to S&S throttle Hog 70mm throttle bodies (2008-up touring applications) * Stock-style breather system—compatible with stock and aftermarket air cleaners * Large 2.200 in. intake and 1.800 in. exhaust valves * Machined for stock sensors—EFI friendly * .660 in. lift S&S valve springs with titanium top collars * Head kits include valves and valve springs * Requires special pistons, pushrods, manifold intake, intake flanges and seals, and an exhaust adaptor kit (sold separately) * Kits do not include gaskets, hardware, or intake and exhaust flanges (these parts must be purchased separately) Fitment: * S&S only stocks the late model 4 1/8 in. bore versions as off-the-shelf items, but heads for other applications and individual front of rear replacement heads available by special order only Possible options by Special Order: (final price varies depending on selected special option requests by customer) * Cylinder head sets without valves or springs individual front, or rear heads * CNC-ported intake and exhaust ports—more air, more power! * Two-bolt exhaust flanges—can accommodate stock exhaust headers, existing 2 in. headers, or build your own 2 in. exhaust system * Machined for 2008—later bagger front motor mount * 4 1/8 in. to 4 3/8 in. bore sizes * Stock 1999-up, S&S, or other cylinder stud patterns—other patterns subject to approval * Machined with or without S&S electric compression release * Choose from a variety of pushrod geometry machining styles * Choose from a variety of different chamber sizes * Individual front of rear heads available by special order * Available in wrinkle black, gloss black, silver, or natural

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
