Intake Gasket - BBC Big Chief (1pk)

The DART Intake Gasket for BBC Big Block Chevy (SKU DRT65002155) is a precision-engineered intake manifold gasket engineered for big block Chevy applications with 14-degree cylinder heads. Built from compressed fiber material, this gasket delivers reliable sealing at the intake manifold interface where port mismatch and thermal cycling demand consistent performance. At 0.06 inches thick, it's sized to match the oval port geometry of big block engines that require exact dimensional specifications for proper manifold-to-head sealing.

The 1.97 x 2.688 inch oval port design accommodates the specific intake port configuration of big block Chevy heads. Compressed fiber construction provides the rigidity needed to maintain gasket crush and prevent leakage under cylinder head clamping load while resisting deformation from manifold bolt torque. This material selection balances durability with compatibility across temperature ranges typical in street and race engine applications. Single-gasket packaging means one unit per order—confirm your engine's specific port configuration against the 1.97 x 2.688 inch oval dimension before purchase to ensure correct fitment.

This gasket is essential for builders and engine shops rebuilding big block Chevy intake systems, whether for street performance, marine applications, or sustained high-output scenarios. Proper intake gasket selection prevents vacuum leaks and fuel-air mixture inconsistencies that degrade idle quality and part-throttle response. The 14-degree head specification makes this gasket critical for engines using modern or modified cylinder head configurations designed around that specific angle—using the wrong gasket thickness or port size invites vacuum leaks and performance loss.
