Tailored precisely to fit the taller deck-height small-block Ford 351-Cubic Inch Windsor V8 engine housed within the iconic XR, XT, XW, and XY Falcon chassis runs, this premium upgrade replaces highly restrictive factory cast iron manifolds. By maximizing exhaust gas scavenging velocity and significantly lowering engine backpressure, it unlocks noticeable low-to-mid range torque, crisp throttle responsiveness, and that signature classic muscle car V8 rumble.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"feature-block\"\u003e\n\u003cdiv class=\"feature-content pb-6\"\u003e\n\u003ch3 style=\"color: #e60000; font-weight: bold;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003ePRODUCT CONTENTS:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Left-Hand Windsor V8 Extractor Header Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Right-Hand Windsor V8 Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCustom clearance-mapped to maintain full compatibility with classic factory Ram-type power steering assist cylinder linkages without binding or physical interference\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity past the constraints of the taller 351 block deck height\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque delivery—ideal for improving throttle crispness, cruising manners, and acceleration curves in street machines and restorations\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and typical classic muscle car vibrations safely\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure exhaust leaks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"specs\"\u003e\n\u003cul class=\"flex flex-col space-y-2 text-xs\"\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eBrand:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eAdvance Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003ePart Number:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eA56\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eMaterial:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eMild Steel (Standard Finish)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEngine Suitability:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eFord Small Block Windsor V8 (351ci Block Only)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eSteering Setup Fitment:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eCompatible with Ram-Type Power Steering Assist Systems\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eComponent Type:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePerformance Exhaust Extractors \/ Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEstimated Fitting Time:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e3 Hours\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWelding Required:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eNo (Direct Bolt-On Configuration to Cylinder Heads)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Engine Variant \u0026amp; Chassis Geometry Fitment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003e351 Windsor V8 Specific Fitment:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA56\u003c\/strong\u003e) is configured and space-mapped strictly for the \u003cstrong\u003e351 Windsor engine footprint\u003c\/strong\u003e, which features a taller deck height and wider intake stance than the 289\/302 Windsor variants.
