Tailored exclusively to accommodate the legendary, high-flowing 351-Cubic Inch Cleveland V8 engine optioned with massive factory \"4V\" Big Port cylinder heads, this kit bridges the gap across a massive vehicle lineage, including XR, XT, XW, XY, XA, XB, XC, XD, XE, and XF Falcon series alongside ZA through ZL Fairlane flagships. By matching the huge port footprint and removing the restrictive bounds of standard iron castings, this setup optimizes high-velocity gas flows to unlock definitive top-end horsepower and a deep, crisp street-machine growl.\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 351C 4V Big Port Extractor Bank Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Right-Hand 351C 4V Big Port Extractor Bank Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngineered specifically to match the ultra-wide opening footprint of authentic Ford 4V \"Big Port\" Cleveland cylinder heads, ensuring zero gas flow turbulence or step restrictions at the header face\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust scavenging velocity across high-RPM working bands\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes top-end horsepower curves and breathing capability—providing the perfect flow foundation for highly modified street cruisers, drag cars, and tough restorations\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and high-vibration muscle car applications 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 gas 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\"\u003eA350\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 351-Cubic Inch Cleveland V8 Only (Must feature 4V Big Port Heads)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eFlange Pattern:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eDedicated 4V Large Rectangular Layout\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\"\u003eClassic Muscle Performance 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\"\u003e2.5 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 Cylinder Head Variant Alignment Warning:\u003c\/strong\u003e\u003cbr\u003eThis product (Part No. \u003cstrong\u003eA350\u003c\/strong\u003e) is configured and clearance-mapped strictly for \u003cstrong\u003eauthentic 4V Big Port Cleveland cylinder head profiles\u003c\/strong\u003e.
