Intake Gasket Set SBM Mag w/Perf RPM Heads

The Edelbrock Intake Gasket Set SBM Mag with Performance RPM Heads is a precision composite gasket pair engineered for small-block Mopar engines equipped with high-flow cylinder heads. This intake manifold gasket delivers reliable sealing on rectangular ports measuring 1.18 x 2.18 inches, with a 0.06-inch thickness designed to maintain consistent compression and prevent vacuum leaks that compromise engine efficiency and drivability.

Composite gasket material in this set provides superior heat resistance and dimensional stability compared to paper gaskets, making it suitable for high-performance applications including modified street engines and track-focused builds. The matched geometry for RPM cylinder heads ensures flush seating across the intake surface, eliminating dead spots that can cause air/fuel ratio inconsistencies. Edelbrock's manufacturing tolerances account for the specific port patterns of Mopar small-block architecture, reducing installation variability and the risk of costly rehang intervals.

Engine builders and Mopar enthusiasts restoring or upgrading 318, 340, and 360 displacement platforms rely on gasket sets matched to their cylinder head choice. This pair addresses the OE-to-performance transition common when upgrading from stock castings to RPM heads, where port timing and alignment shift measurably. Proper gasket selection at this junction prevents intake manifold vacuum leaks that result in rough idle, stumble on acceleration, and elevated emissions. The lightweight composition (0.35 lbs) facilitates handling during intake manifold installation without requiring additional fastener torque adjustments.
