Pacemaker Headers PH4090 – Ford Falcon XR–XY 302 & 351 2V Cleveland V8

Pacemaker PH4090 headers (extractors) are a high-performance upgrade designed for Ford Falcon XR, XT, XW and XY fitted with 302 and 351 2V Cleveland V8 engines. Precision-engineered to improve exhaust flow, these headers increase torque, sharpen throttle response, and deliver a stronger, more aggressive exhaust note.

With larger primary and collector sizing, PH4090 headers are suited to modified and higher-output Cleveland builds requiring improved airflow and reduced restriction, while maintaining reliable fitment and durability.

Why Good Headers and Exhaust Systems Matter

• At 5000rpm, a 351 Cleveland moves approximately 12,200L/min intake airflow and expels around 36,600L/min exhaust gas [@600°C]
• At 6500rpm (600hp), airflow increases to approximately 22,000L/min intake and 66,000L/min exhaust output
• Efficient headers improve scavenging, reduce restriction and support horsepower and torque gains

Warranty & Compliance

• Backed by Pacemaker’s 2-year manufacturer warranty
