Unlike standard Windsor headers, these feature a Tri-Y design with large 1¾\" (44mm) primary pipes that step into 2\" (51mm) secondaries, ultimately flowing into a 3\" (76mm) outlet. This configuration is ideal for maximizing mid-range torque and high-end horsepower in classic Falcon and Fairlane models. Whether you are running a period-correct XR-XY or performing an engine swap into later chassis, these Australian-made headers provide the precision fitment and superior flow required for competition-level performance.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cp\u003eThis product offers the following high-performance features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpread Port Compatibility:\u003c\/strong\u003e Designed exclusively for 351 Windsor heads featuring the wider dual bolt pattern.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompetition Tri-Y Design:\u003c\/strong\u003e Optimized for a broad power band and increased exhaust gas velocity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Piping:\u003c\/strong\u003e 1¾\" (44mm) primary and 2\" (51mm) secondary mandrel-bent pipes for maximum flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge 3\" Outlet:\u003c\/strong\u003e 3\" (76mm) collectors support high-horsepower engine configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Fitment Range:\u003c\/strong\u003e Suitable for original XR-XY Falcons and a wide variety of Ford engine swap models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"font-family: Arial, sans-serif; max-width: 100%; padding: 20px; border: 1px solid #ccc; border-radius: 5px; font-size: 14px; margin-bottom: 20px;\"\u003e\n\u003cstrong\u003eProduct Specifications for PH4036 L\/R\u003c\/strong\u003e\n\u003cdiv style=\"width: 100%; overflow-x: auto; margin-top: 10px;\"\u003e\n\u003ctable style=\"min-width: 800px; border-collapse: collapse; width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f0f0f0; border-bottom: 2px solid #333;\"\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eValue\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003ePart #\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003ePH 4036\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eOutlet\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e3\" (76mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003ePrimary Pipe\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e1¾\" (44mm)\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eSecondary Pipe\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e2\" (51mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eP\/Steering\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eYes\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eAir Con\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eFitting Time\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e3½ Hrs\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eGasket\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eImportant Notes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e This product will \u003cstrong\u003eNOT\u003c\/strong\u003e fit standard Windsor heads.
