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.

Continental Conti V Torque Team Supreme (formerly Torque Team Plus) belts are their highest capacity V-belts and known for strength, durability, and performance. The tension members are Aramid cords twisted from Aramid fiber, which is five times stronger than steel, then treated for improved adhesion, improved flex life, and increased resistance to shrinkage. These belts exhibit only one-half of the initial elongation of polyester belts and maintain greater dimensional stability over the life of the belt. They stand up to higher horsepower, high-tension drive requirements, shock loads and abusive installations better than standard joined belts, multiple V-belt teams, or chain and sprocket drives. The cushion is made of a highly engineered compound that resists harsh operating environments and compression fatigue. The fabric wrapping is also rubber compound-impregnated to protect the carcass from abrasion, heat, ozone, and oil. The backing prevents materials from penetrating the belt, keeping your operation running longer. Together, these components offer a strong, flexible, and efficient belt with extended service life. Don't settle for anything less than the precision engineered Continental Conti V Torque Team Supreme industrial V-belts designed to provide perfect fit, form, and function for your application. Product features, items, and specifications include: * Decreased drive weight * Reduced maintenance, vibration, and turn over * Working (outside) temperature range of -40 degrees C (-40 degrees F) to 60 degrees C (140 degrees F) * Anti-static in accordance with ISO 1813 * Conditionally resistant to oil
