Flange Gasket 1150/1250 CFM Carbs 4-Hole

The Flange Gasket 1150/1250 CFM Carbs 4-Hole is a precision carburetor base plate gasket designed for high-performance four-barrel carburetors in the 1150–1250 CFM flow range. This gasket is ideal for applications involving Holley Dominator platforms, ensuring a reliable seal between the carburetor body and intake manifold.

Manufactured from composite material and rated at 0.063 inches thick, this gasket is engineered to withstand the thermal and pressure cycling inherent in both fuel-injected and carbureted engine applications. Its composite construction balances durability with compliance, preventing carburetor base plate warping while maintaining a consistent seal across the mounting surface.

This gasket is essential for carburetor rebuilds, intake manifold replacements, or seasonal engine maintenance on muscle cars, hot rods, and performance trucks running Holley four-barrel carburetors. The four-hole configuration aligns precisely with Dominator carburetors and compatible manifold ports, ensuring uniform clamping load distribution and eliminating hot spots that can cause fuel vaporization or air bypass.
