Edelbrock Performer Cylinder Head for 4.0L Jeeps


Torrance, CA - {February 26, 2015}
Edelbrock is excited to announce the release of its new cylinder head for 1987-2006 Jeeps with a 4.0L inline six cylinder engine.

This new Performer cylinder head is designed as a bolt-on performance upgrade for 1987-2006 Jeeps with a 4.0L inline six cylinder engine. It features all-new better flowing intake and exhaust ports, a modern combustion chamber design with back cut and swirl polished valves. It retains the stock valve angle, pushrod length and valve cover bolt rail height for use with factory components and off the shelf accessories. It also features larger reinforced rocker bosses for improved strength at high RPM and Heli-CoilŪ threaded inserts in the manifold bolt holes for added strength. A 3/4" deck throughout the head also provides improved durability. It's machined to accept either distributor or coil pack ignition.

The Performer Jeep 4.0L is designed with 1991-2006 4.0L intake port locations and must be used with 1991-2006 intake manifold. The Performer Jeep 4.0L is designed with 1991-98 4.0L exhaust port locations and must be used with 1991-98 factory header or 19991-2006 aftermarket exhaust header. This cylinder head will also fit 1976-90 AMC 4.2L engines with no modification to the water jacket and the appropriate intake manifold and header combination.

This cylinder head is pending 50-state emission legal for 4.0L engines when used with factory fuel injection components. It's also pending 50-state emission legal for AMC 4.2L engines when used with a Mopar Fuel Injection Conversion Kit (E.O. Number D-265-21).

Features Include:

  • Designed for 1987-2006 Jeep 4.0L inline six cylinder engines
  • Can be used with 1976-90 AMC 4.2L engines with no modification to the water jacket and the appropriate intake manifold and header combination
