Metering Block Gskt 2pk Holley 4150-4500

The Metering Block Gskt 2pk Holley 4150-4500 is a precision carburetor gasket pair engineered for serious carb tuners and engine builders working with classic and high-performance Holley four-barrel platforms. This reusable composite gasket addresses one of the most critical sealing points in carburetor assembly: the metering block interface. Whether you're rebuilding a vintage muscle car engine, restoring a street rod, or dialing in a competition carb setup, a quality metering block gasket prevents fuel and air leaks that compromise jetting accuracy and engine performance.

SCE Gaskets engineered this metering block gasket from composite material rated at 0.063 inches thick, offering the durability needed for repeated carburetor service cycles without permanent compression set. The red composite construction resists fuel degradation and maintains a reliable seal across temperature swings typical in engine bays, whether running pump gas or race fuel. The two-pack format ensures you have a replacement gasket on hand for future rebuilds, eliminating downtime when you're tuning or troubleshooting fuel delivery issues across your Holley 4150 or 4500 carburetors.

Mechanics and engine builders rely on this gasket kit when performing carb rebuilds, fuel bowl repairs, or metering system adjustments on Holley 4150 and 4500 series carburetors—the industry standard for street, strip, and vintage racing applications. Proper metering block sealing prevents external fuel weeps and internal bypass leaks that throw off your air-fuel ratio tuning. Installation is straightforward: replace the old gasket during disassembly, ensure mounting surfaces are clean and flat, and torque fasteners evenly to spec. Stock this two-pack in your shop or keep it in your toolbox for any Holley carb work.
