Review HARLEY DAVIDSON New Genuine 131 Extreme Ported Cylinder Heads fits SCREAMIN EAGLE M8

The Harley-Davidson Screamin' Eagle 131 M8 Extreme Cylinder Heads are a high-performance upgrade for Harley-Davidson Touring motorcycles with Twin Cam 103 and Twin Cam 110 engines. These cylinder heads are a direct replacement for the OEM heads, and they provide significant power and torque gains to enhance the riding experience.

The 131 M8 Extreme Cylinder Heads feature lightweight titanium intake valves and heavy-duty steel exhaust valves. The intake valves are larger than the OEM valves, providing improved airflow into the engines, while the exhaust valves are designed to optimize exhaust gas flow for enhanced engine breathing. The valves are actuated by longer, stronger pushrods and high-performance roller rockers, providing improved valve control and reducing friction.

The cylinder head combustion chambers are CNC machined and feature a shallower, more aggressive profile to optimize fuel/air mixtures and enhance combustion efficiency. The hotter combustion temperatures produced by the Extreme Cylinder Heads require the use of a high-performance combustion ring set, which is included in the kit.

The intake ports on the Extreme Cylinder Heads have been Flow Bench tested and are designed to maximize intake flow, while the exhaust ports are specifically designed to optimize exhaust flow and scavenging. The heads also feature electric water pump coolant passages to improve cooling efficiency.

The 131 M8 Extreme Cylinder Heads are designed to work in conjunction with a tuned aftermarket fuel system, such as an EFI system or carburetor setup, to provide optimal performance and reliability. Installation of these heads requires the use of a camshaft that is compatible with the increased intake and exhaust flows.

In summary, the Harley-Davidson Screamin' Eagle 131 M8 Extreme Cylinder Heads are a top-tier performance upgrade for Harley-Davidson Touring motorcycles. They provide significant power and torque gains through improved airflow, increased combustion efficiency, and enhanced exhaust gas scavenging. These heads are designed with high-quality materials and manufacturing processes to provide durability and reliability, making them a popular choice among Harley riders looking to maximize performance from their motorcycle.
