Holden 304 Intake Manifold & Carby Conversion Options

This page compares two dual plane intake manifold configurations that may be relevant to a Holden 304 build. The correct manifold depends on the installed cylinder heads, intake-port layout, bolt pattern, carburetor flange and overall installation clearance.

EVBUH0006005 is listed for compatible Holden V8 applications using 1988–98 VN-style cylinder heads and a 4-barrel square-bore carburetor flange. EVBUH0006003 is a Holden 304 carby manifold option that uses a square/spread-bore flange, but its exact Holden 304 cylinder-head fitment should be verified before purchase.

Check Holden 304 Cylinder Heads Before Ordering
A Holden 304 intake manifold should not be selected by engine displacement alone. First identify the installed Holden 304 cylinder heads and compare the intake ports and manifold mounting points with the intended manifold.

Confirm the installed Holden 304 heads.
Compare the intake-port layout.
Check the Holden 304 bolt pattern.
Confirm the required carburetor flange.
Check the Holden 304 intake manifold gasket.
Confirm the required intake manifold bolts.
Check manifold, carburetor and air-cleaner height.
Verify hood clearance before installation.

If any of these details are unknown, complete the fitment-check form before ordering.

Compare Holden 304 Dual Plane Intake Manifold Options

EVBUH0006003 and EVBUH0006005 are both dual plane carburetor manifolds, but they should not be treated as interchangeable style or color options. Cylinder-head requirements, carburetor flange, listed RPM range and overall dimensions differ between the two products.

EVBUH0006003: Square/spread-bore carburetor flange, listed 2,500–4,800 RPM range and 21.18 × 11.5 × 4.86 in dimensions. Holden 304 cylinder-head fitment requires confirmation.
EVBUH0006005: Listed for compatible 1988–98 VN-style cylinder heads, 4-barrel square-bore carburetor flange, 3,200–5,600 RPM range and 21.53 × 13.63 × 6.08 in dimensions.

Compare the complete fitment information before choosing either Holden 304 dual plane intake manifold.

Planning a Holden 304 Carby Conversion?

A Holden 304 carby conversion involves more than changing the intake manifold. The installed cylinder heads, carburetor flange, fuel-system configuration, distributor arrangement, gasket, mounting hardware and available clearance should all be checked as part of the conversion.

Neither intake manifold should be described as a complete Holden 304 carby conversion kit unless every required conversion component is specifically listed as included on the product page. Review the package contents and identify any additional installation parts before ordering.
