Pacemaker Tri-Y Competition Headers - 351 Windsor Spread Port Head - PH4036 L/R

Engineered for high-performance small block Ford builds, the Pacemaker PH4036 Competition series headers are designed specifically for the 351 Windsor engine equipped with Spread Port / Dual Bolt Pattern cylinder heads. 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.

Features:

This product offers the following high-performance features:

  • Spread Port Compatibility: Designed exclusively for 351 Windsor heads featuring the wider dual bolt pattern.
  • Competition Tri-Y Design: Optimized for a broad power band and increased exhaust gas velocity.
  • Heavy-Duty Piping: 1¾" (44mm) primary and 2" (51mm) secondary mandrel-bent pipes for maximum flow.
  • Large 3" Outlet: 3" (76mm) collectors support high-horsepower engine configurations.
  • Broad Fitment Range: Suitable for original XR-XY Falcons and a wide variety of Ford engine swap models.

Great cleaner, smells nice!
Scent: Lemon
I use half a bottle and mix with water--great all-purpose cleaner and it doesn't have a horrible chemical scent. It smells nice and cleans well. I buy this on a subscription.

I am extremely satisfied with this product! It worked even better than I expected. The plastic on my car looks like new again—deep, rich color and a nice clean finish. The application process was simple and quick, and a little product goes a long way. I also love how long-lasting the results are. After several washes, it still looks great and provides solid protection. Definitely a high-quality product that delivers on its promises. I highly recommend it 100% to anyone looking to restore and protect their car’s plastic surfaces!
