    Magnum Cylinder Heads with "LA" Intake Holes

    Note: Outflows stock and Magnum R/T cylinder heads (no longer available from Mopar)

    This cylinder head is a stock replacement on 1992-2001 5.2L Magnum and 1993-2003 5.9L Magnum engines. It can also be used on 1964-1991 small block Mopar engines, but must be used with the following conversion parts:

    • Flat top or dished pistons (small 62 cc closed chamber on head)
    • 10-Bolt Magnum Valve Covers 312-P5007611AB & Gasket 312-P5249660
    • Magnum Rocker Arms 312-P4876050 (8 required) or Similar
    • Hollow Tube Style 5/16" Hardened Pushrods (oils heads) with Approx. Length = 7.625"
    • Hydraulic Flat Tappet Style Camshaft
    • AMC V8 Style Tappets with Oil Passage (oils heads) 312-P4529220AB or Similar (for hydraulic flat tappet cam only)
    • 1964-1991 Small Block Intake Manifold
    • Intake Manifold Gasket Set 312-P4876049, 326-615-310, or 350-7277
    • Head Bolt Set 555-83446

    Minor machining may be required for pushrod & rocker arm clearance. The pushrods and tappets must have hollow oil passages since Magnum heads are oiled through these components.

    Cast Iron Replacement Heads for Magnum 5.2L/5.9L Engines

    Stock Mopar Magnum Cylinder Heads have induction hardened exhaust valve seats that are prone to cracking. To fix the problem, JEGS replacement cast iron cylinder heads incorporate stronger exhaust valve seats. JEGS Magnum Cylinder Head is also available with LA-style intake screws to accommodate 1964-1991 small block Mopar intake manifolds, ideal for high performance.


    • For Dodge/Chrysler Magnum Engines: 1992-2001 5.2L and 1993-2003 5.9L
    • JEGS Design Improves Flow & Exhaust Valve Seats
    • Accepts All Stock Magnum Components
    • Intake Port Volume: 172cc
    • Combustion Chambers: 62cc
    • Valves: 1.920" Intake, 1.624" Exhaust with 8mm Valve Stems
    • Optional "LA" Screw Holes Allow Use of Early Mopar Intake Manifold
    • Bare or Assembled Cylinder Head (Sold individually unless part of kit)
    • Assembled Cylinder Heads Include Valves, Springs (Accepts up to 0.510" Gross Valve Lift), Retainers, and Keepers

    Do you have an option to change the valve springs to a .550 lift vs the stock 511 that come on these heads? I plan on running around a 533 lift.

    You would need to purchase the springs rated for the camshaft you want to use and change them.
