Bb.Chevy Intake Gaskets RECT PORT 1.82in x 2.54i

The FEL-PRO Bb.Chevy Intake Gaskets RECT PORT 1.82in x 2.54in (MPN 1275) is a precision-engineered intake manifold gasket designed specifically for big block Chevrolet engines requiring rectangular port configuration. Built by FEL-PRO, a manufacturer trusted across law enforcement and military vehicle maintenance operations, this gasket serves as a critical sealing component between the intake manifold and cylinder head. Proper intake gasket sealing is essential to maintain compression integrity, prevent coolant and oil crossover leaks, and ensure optimal engine performance and longevity in both duty and off-road applications.

This intake gasket features a composite construction with a nominal thickness of 0.06 inches, engineered to withstand the thermal cycling and pressure loads characteristic of big block Chevrolet powerplants. The rectangular port configuration measures 1.82 x 2.54 inches, matching OEM big block intake port dimensions for precise alignment and uniform sealing surface contact. The composite material composition provides superior chemical resistance to coolant and fuel additives while maintaining dimensional stability across extended temperature ranges—critical for vehicles subjected to sustained high-load operation or extreme environmental conditions.

Operators and technicians performing intake manifold service on big block Chevy engines will find this gasket essential for preventing vacuum leaks and coolant seepage that compromise drivability and engine reliability. The kit format allows for complete gasket set replacement during manifold removal, eliminating the need for sourcing multiple components separately. Installation requires standard manifold torque procedures and careful surface preparation of both mating surfaces to ensure lasting seal integrity. Weighing 0.37 lbs and packaged in compact 5.8 x 0.5 x 26.85 inch dimensions, this gasket kit represents OEM-quality engineering for tactical fleet maintenance, restoration, and high-performance applications.
