Pontiac SD Intake Gasket 1.90in x 2.70in SPREAD

The FEL-PRO Pontiac SD Intake Gasket 1.90in x 2.70in Spread Port (SKU FEL1249, MPN 1249) is a composite intake manifold gasket engineered for big block Chevy engine applications requiring reliable sealing at the intake manifold-to-cylinder head interface. This 0.06-inch thick gasket features rectangular spread ports sized at 1.9 x 2.7 inches, matching OEM specifications for Pontiac SD engine platforms. FEL-PRO gaskets are manufactured to stringent OEM tolerances, ensuring proper cylinder pressure containment and preventing coolant or oil seepage at critical engine seals.

The composite construction of this intake gasket provides balanced performance across temperature cycling and thermal stress common to high-output big block Chevy engines. The 0.06-inch thickness is engineered to maintain consistent clamping load across the manifold mounting surface while accommodating minor warpage on vintage or heavily used cylinder heads. Proper gasket selection prevents vacuum leaks that compromise idle quality, fuel mixture accuracy, and emissions control system function. The 1.90 x 2.70-inch port opening matches the spread-port design found on specific Pontiac SD platforms, ensuring precise alignment with intake runner geometry.

This gasket is essential for engine builders, restoration specialists, and mechanics performing intake manifold removal or replacement on Pontiac big block applications. Whether rebuilding a vintage muscle car engine, addressing coolant seepage, or upgrading to an aftermarket intake manifold, correct gasket selection prevents costly re-work and ensures sealed assembly on first installation. The FEL1249 composite gasket is a direct replacement for OEM intake sealing and is compatible with both stock and performance intake manifold configurations designed for the Pontiac SD big block platform.
