Holden VN Heads 308 304 Low-Rise Single Plane Intake Manifold

Maximize carburetted Holden V8 power with the Holden VN Heads 308/304 Low-Rise Single-Plane Intake Manifold. Finished in natural cast, this non-EGR intake is engineered to deliver a steady, even air and fuel flow across the engine for improved performance and efficiency in the 1500–6500 RPM range.

• Low-rise single-plane design to optimize airflow in tight engine bays while preserving throttle response and peak power.
• Carburettor mounting pad is spread bore, compatible with aftermarket spread-bore carbs, with options for both manual and electric choke.
• Non-EGR configuration tailored for carburetted Holden V8 applications; specifically designed for late model VN engine models.
• Fits Holden 304 V8 engines. Will not suit early Holden 308 cylinder heads. Not compatible with VT engines that have factory roller camshafts.
• Designed for Holden 253/308 V8 engines operating from 1500 to 6500 RPM, with a focus on maximizing power through optimized air/fuel distribution.
• Most late-model water necks, air conditioning, alternator, and HEI ignition systems can be accommodated; intake runners should be port-matched to your cylinder heads for best results.

Whether you’re upgrading a carburetted build or aiming to extract additional power from a VN-era Holden, this low-rise intake manifold provides a purpose-built solution with precise flow characteristics and practical compatibility notes to help you plan your install.
