They feature better flowing intake\/exhaust ports along with a modern combustion chamber design and back cut and swirl polished valves for improved flow. Retains the stock valve angle, pushrod length and valve cover bolt pattern for use with factory components and off the shelf accessories. Larger reinforced rocker bosses for improved strength at high RPM and Heli-Coil threaded inserts in the intake manifold bolt holes for added strength as well as a 3\/4 deck throughout the head also promotes stiffness and durability. This cylinder head is machined to accept both distributor or coil pack ignition. To optimize airflow, this cylinder head is designed with a 1991-2006 4.0L intake port location and 1991-98 4.0L exhaust port size. As a result, this cylinder head must be used with a 1991-2006 intake manifold and a 1991-1998 exhaust manifold. Aftermarket exhaust headers can also be used in place of 1991-1998 exhaust manifolds and MUST be used in place of 1999-2006 exhaust manifolds. Most aftermarket exhaust headers are compatible, but please check with the exhaust header manufacture to verify. This head is NOT compatible with 1999-2006 OEM exhaust manifolds.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eCamshaft Type: Flat Tappet\u003c\/li\u003e\n\u003cli\u003eCNC Ported: No\u003c\/li\u003e\n\u003cli\u003eConstruction Type: Complete\u003c\/li\u003e\n\u003cli\u003eDeck Thickness: 0.750 IN\u003c\/li\u003e\n\u003cli\u003eEGR Port: No\u003c\/li\u003e\n\u003cli\u003eExhaust Port Location: Standard\u003c\/li\u003e\n\u003cli\u003eExhaust Runner Volume: 77 CCM\u003c\/li\u003e\n\u003cli\u003eExhaust Valve Diameter: 1.50 IN\u003c\/li\u003e\n\u003cli\u003eFamily: Performer\u003c\/li\u003e\n\u003cli\u003eGuide Material: Manganese Bronze\u003c\/li\u003e\n\u003cli\u003eHorsepower: 200-300 HJ\u003c\/li\u003e\n\u003cli\u003eIntake Valve Diameter: 1.91 IN\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\u003c\/li\u003e\n\u003cli\u003eValve Angle: 10 DD\u003c\/li\u003e\n\u003cli\u003eValve Lock Material: Steel\u003c\/li\u003e\n\u003cli\u003eValve Spring Diameter: 1.26 IN\u003c\/li\u003e\n\u003cli\u003eValve Spring Maximum Lift: 0.540 IN\u003c\/li\u003e\n\u003cli\u003eValve Stem Diameter: 0.3125 IN\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eEdelbrock Jeep Cylinder Head\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003e1987-2001 Jeep Cherokee\u003c\/li\u003e\n\u003cli\u003e1987-1992 Jeep Comanche\u003c\/li\u003e\n\u003cli\u003e1993-2004 Jeep Grand Cherokee\u003c\/li\u003e\n\u003cli\u003e1987-1990 Jeep Wagoneer\u003c\/li\u003e\n\u003cli\u003e1991-1995,1997-2006 Jeep Wrangler\u003c\/li\u003e\n\u003cli\u003e1997-2006 Jeep TJ\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":52773709971819,"sku":"EDE-50169","price":1933.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/EDE-50169-1.jpg?v=1768811883","url":"https:\/\/caautoparts.com\/products\/jeep-cherokee-comanche-wrangler-tj-cylinder-heads-ede50169","provider":"CA Auto Parts","version":"1.0","type":"link"}
