Why put your bike engine back together with stock parts—when you can upgrade with one of the S&S Cycle flywheel assemblies? These 3-piece units are forged and heat-treated from 4140 steel, making them harder and stronger than stock. They're precision-machined to be truer (for less vibration), and are assembled with integral mainshafts and lightweight connecting rod forgings. Stock flywheels shift out of true under heavy loads; improve your motorcycle with an S&S Cycle flywheel assembly.

Twisted Wedge® 11R 227 cylinder heads represent Trick Flow's ultimate development of the Twisted Wedge® innovation, featuring Trick Flow's most efficient combustion chamber design. The combustion chamber and valve layout move the intake valves away from the cylinder walls to reduce valve shrouding, significantly improving flow at higher lift. Shallow 11° intake/13° exhaust valve angles improve piston-to-valve clearance for high lift cams and reduce chamber volume for improved compression and efficiency. High velocity runners are optimized on the flow bench and dyno proven to outperform the competition on hydraulic roller camshaft engines. Premium materials and components, along with world-class CNC processes, guarantee uncompromising quality and durability, dimensional accuracy, and balanced flow from port-to-port. Machined castings increase strength and have a billet-like appearance. Additional features include CNC-profiled combustion chambers, 2.080"/1.600" stainless steel intake/exhaust valves, Trick Flow® by PAC Racing valve springs, and titanium retainers. Twisted Wedge® 11R 227 heads have CNC Competition Ported runners with a premium high- resolution finish for ultimate performance. Cylinder heads are available fully assembled or as bare castings. Sold individually. Key Features: • 227cc intake ports and 56cc or 66cc combustion chambers • 2.080 in. stainless steel intake valves • 1.600 in. stainless steel exhaust valves • .625" thick deck • Titanium retainers • 11 degree intake valve angle • 13 degree exhaust valve angle

Trick Flow® PowerPort® 270 Max Wedge-style cylinder heads will significantly improve the power of your big block Mopar right out of the box. How? Well for starters, PowerPort® 270 heads are made from premium grade A356-T61 aluminum. That's important because it weighs a lot less than cast iron and is very strong. Trick Flow® engineers fixed the shortcomings of the factory head design by relocating the oil holes for the rocker shafts and optimizing the shape of the runners to increase flow velocity and add much needed strength to the shaft bosses. PowerPort® 270 heads also feature larger, raised Max Wedge-style intake runners that provide a straighter path to the valve for improved airflow. The runners are treated to Trick Flow's® signature high resolution CNC Competition Ported surface finish that guarantees proper dimensional accuracy with balanced flow from runner-to-runner for maximum power potential. Additional advantages of PowerPort® 270 heads include clearance for 3/8 in. pushrods, ductile iron valve seats, bronze alloy valve guides, and multi-angle valve seat machining on precision Serdi® equipment. Assembled cylinder heads come with premium 11/32 in. stainless steel valves, Trick Flow® by PAC Racing valve springs, chromoly and titanium retainer options, and 7 or 10-degree steel valve stem locks. They are available fully assembled or as bare castings. Sold individually. Since swapping cylinder heads can be a costly and time-consuming process, Trick Flow® designed the PowerPort® 270 heads to use all factory-style big block Mopar pistons. They also are manufactured to accept aftermarket roller rocker arms, and headers. A Max Wedge-style intake manifold is recommended for best performance.

Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in.
