Custom-engineered specifically to clear the massive structural dimensions of the high-performance 5.4-Litre (330ci) 4-Valve Dual Overhead Cam (DOHC) Boss V8 engine housed within the BA and BF Falcon XR8, GT, GT-P, and FPV variants, this premium header upgrade completely replaces the highly restrictive factory cast iron log manifolds. By optimizing exhaust gas scavenging velocity and significantly dropping engine backpressure, it unlocks noticeable low-to-mid range torque, explosive top-end throttle response, and a deep, aggressive V8 growl worthy of Ford's iconic muscle platforms.\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 5.4L 4V Boss Extractor Header Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Right-Hand 5.4L 4V Boss Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngineered specifically to seamlessly integrate with the uniquely wide DOHC Boss V8 engine profiles inside BA-BF engine bays, clearing steering shafts, crossmembers, and starter motors\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing high-velocity exhaust gas flow and eliminating turbulence bottlenecks\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes power bands across the entire RPM curve—ideal for improving street throttle crispness, overtaking power, and circuit performance profiles\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-bonnet thermal expansion cycles and typical high-torque performance V8 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\"\u003eA64\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 Modular 5.4L 4-Valve DOHC V8 Only (Boss 260, Boss 290, and FPV Variants)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eCylinder Head Architecture:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eFits 4-Valve DOHC Cylinder Heads Only\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\"\u003e4 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; Valve Architecture Alignment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrictly 4-Valve DOHC Boss V8 Models Only:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA64\u003c\/strong\u003e) is designed and space-mapped exclusively for the high-deck \u003cstrong\u003e5.4L 4-Valve Boss engine footprint\u003c\/strong\u003e.
