Intake Gasket SBC 350 Vortec

The Intake Gasket SBC 350 Vortec by Mr. Gasket is engineered for small-block Chevy engines requiring reliable, precision sealing at the intake manifold. This composite gasket set addresses a critical pressure boundary where intake air meets cylinder head, a junction that demands both durability and thermal stability. Anyone restoring, rebuilding, or maintaining a small-block Chevy 350 with Vortec-style ported heads will benefit from this OEM-grade replacement, which prevents vacuum leaks, coolant seepage, and combustion gas blowby that degrade engine efficiency and reliability.

This intake gasket features a composite material construction and maintains a 0.12-inch thickness to match factory Vortec port geometry precisely. The gasket pair is cut to accommodate 1.31 x 2.37-inch Vortec port dimensions, ensuring complete coverage without gap or overhang that would compromise the seal under combustion chamber pressure and temperature cycling. Composite construction provides superior resistance to coolant degradation and heat-induced delamination compared to cork or asbestos-based gaskets, extending service life across thousands of engine cycles and temperature swings inherent to high-performance or daily-driver applications.

Mechanics, engine builders, and enthusiasts performing intake manifold removal—whether for coolant circulation repair, manifold gasket replacement, or cylinder head work—will find this Mr. Gasket set essential for reinstallation. The pair format covers both sides of the manifold-to-head interface, eliminating the need for partial gasket sourcing during reassembly. Installation requires proper torque sequencing and surface preparation; cleaning all old gasket material and applying a light bead of anaerobic sealant ensures maximum leak prevention when reassembling the manifold onto Vortec-ported small-block Chevy heads at specification torque values.
