It's designed to fit with the stock intake manifold, exhaust manifold, valve cover, rockers, spark plugs and accessories, as well as Hellcat components. this cylinder head have been machined to be used on either the driver or passenger side of the block. They are cast from A356 aluminum and heat treated to T6 specifications, machined and assembled at Edelbrock's facility in Torrance, California for guaranteed quality. The Edelbrock 61099 Performer RPM cylinder head features fully CNC machined combustion chambers along with CNC profiled bowls and port entries\/exits for improved air flow. 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. 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 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. Match with an Edelbrock Victor EFI 7179 intake manifold for the ultimate in Edelbrock Gen III HEMI performance.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eCamshaft Type: Hydraulic Roller\u003c\/li\u003e\n\u003cli\u003eCNC Ported: No\u003c\/li\u003e\n\u003cli\u003eConstruction Type: Complete\u003c\/li\u003e\n\u003cli\u003eDeck Thickness: 0.625 IN\u003c\/li\u003e\n\u003cli\u003eEGR Port: No\u003c\/li\u003e\n\u003cli\u003eExhaust Port Location: Eagle\u003c\/li\u003e\n\u003cli\u003eExhaust Runner Volume: 75 CCM\u003c\/li\u003e\n\u003cli\u003eExhaust Valve Diameter: 1.650 IN\u003c\/li\u003e\n\u003cli\u003eFamily: Performer RPM\u003c\/li\u003e\n\u003cli\u003eGuide Material: Manganese Bronze\u003c\/li\u003e\n\u003cli\u003eHorsepower: 450-700 HJ\u003c\/li\u003e\n\u003cli\u003eIntake Valve Diameter: 2.165 IN\u003c\/li\u003e\n\u003cli\u003ePush Rod Diameter: (Suggested) Stock\u003c\/li\u003e\n\u003cli\u003eQuantity: Sold Individually\u003c\/li\u003e\n\u003cli\u003eRetainer Included: Yes\u003c\/li\u003e\n\u003cli\u003eSeat Angle: Exhaust 45 deg\/Intake 45 DD\u003c\/li\u003e\n\u003cli\u003eSeat Material: Ductile Iron\u003c\/li\u003e\n\u003cli\u003eSeries: Performer RPM\u003c\/li\u003e\n\u003cli\u003eValve Angle: Exhaust 16.8 deg\/Intake 18.8 DD\u003c\/li\u003e\n\u003cli\u003eValve Lock Material: Steel\u003c\/li\u003e\n\u003cli\u003eValve Spring Diameter: 1.066 in\/ 1.300 IN\u003c\/li\u003e\n\u003cli\u003eValve Spring Maximum Lift: 0.680 IN\u003c\/li\u003e\n\u003cli\u003eValve Stem Diameter: 0.314961 IN\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eEdelbrock HEMI GEN III Cylinder Head\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":52773699649899,"sku":"EDE-61099","price":1639.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/EDE-61099-1.jpg?v=1768812880","url":"https:\/\/caautoparts.com\/products\/cylinder-heads-ede61099","provider":"CA Auto Parts","version":"1.0","type":"link"}
