Advance Headers High-Performance Mild Steel Conversion Extractors for HOLDEN Commodore VB to VL 5.0L EFI V8 Engine Swaps
The Advance Headers Performance Engine Conversion Extractors (A314D) are precision-engineered for first-generation classic Holden Commodore VB, VC, VH, VK, and VL platforms undergoing a later-generation 5.0-Litre 304ci Fuel-Injected (EFI) V8 engine swap. Featuring a premium dual-outlet header configuration, this heavy-duty tubular system is mapped specifically to handle the structural changes required when dropping the modern high-port symmetrical EFI V8 block into early-model engine bays. It replaces highly restrictive custom configurations or stock cast iron log manifolds to maximize exhaust gas scavenging velocity and deliver an aggressive, balanced V8 roar.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Conversion Exhaust Extractor Header Set (Left & Right Dual Outlet Assembly)
Key Features:
- Premium dual-outlet design configuration isolates cylinder exhaust tracks more efficiently down through dual primary paths for minimized high-RPM backpressure
- Tuned mandrel-bent primary piping pathways map perfectly to high-port symmetrical VN-style EFI cylinder heads, ensuring uniform gas flow routing and maximizing engine efficiency
- Substantially optimizes low-to-mid range torque delivery and throttle response—giving your retrofitted street cruiser or custom street/strip machine a huge performance gain
- Heavy-duty mild steel construction structurally built to handle intense under-hood thermal transitions and demanding engine conversion operating environments safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping and high-pressure exhaust leaks
Specifications:
- Brand: Advance Headers

- Header Configuration: Dual Outlet System Layout
- Component Type: Performance Exhaust Conversion Extractors / Headers
- Estimated Fitting Time: 2.5 Hours
- Welding/Modification Required: Yes (Requires downstream dual-pipe exhaust fabrication to complete layout connection)
⚠️ Crucial Engine Conversion Fitment & Application Warnings:
1. Conversion Specifics Only: This product (Part No. A314D) is intended strictly for engine swap applications where a later-model 5.0L EFI fuel-injected V8 engine is being retrofitted into an early VB, VC, VH, VK, or VL Commodore chassis. It will not align with factory-fitted VN-VS models or early carburetted 253/308 cylinder heads.
2. Downstream Dual Outlet Layout: Being a dedicated dual-outlet header design, this assembly does not converge into a single pipe under the gearbox. Your vehicle must be fitted with a custom or aftermarket dual exhaust system, and custom fabrication will be required to interface the headers with downstream piping components cleanly.
Please Note: Due to the custom tolerances involved in engine swap conversions, professional installation by an exhaust specialist or a qualified conversion mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
