Intake Gasket Set - BBC Ret-Port 1.800 x 2.500

The MAHLE ORIGINAL/CLEVITE Intake Gasket Set for Big Block Chevy with 1.800 x 2.500 rectangular port specifications is a composite-construction intake manifold gasket kit engineered for reliable sealing on high-displacement big block engines. Manufactured to OEM-equivalent tolerances, this gasket set provides dependable compression sealing at the intake manifold-to-head interface, where combustion pressure and thermal cycling demand precision fit and material integrity.

Composite gasket construction balances material durability with thermal management across the intake port surfaces. The 0.06-inch thickness and 1.8 x 2.5-inch rectangular port dimensions are specifically dimensioned for big block Chevy applications, ensuring proper sealing pressure distribution without over-compression. Port geometry matches factory intake manifold specifications, eliminating guesswork during installation. This gasket kit design accommodates the flow characteristics and expansion rates typical of big block powerplants, where seal integrity directly impacts combustion efficiency and prevents coolant or fuel vapor leakage into the crankcase.

Owners performing intake manifold service, rebuild, or reseal operations on big block Chevy engines—whether in performance vehicles, marine applications, or heavy-duty builds—rely on OEM-spec gasket sets to avoid repeat disassembly. This kit addresses the most common intake-to-head sealing requirement on BBC platforms. Proper gasket selection and installation ensure stable idle quality, prevent vacuum leaks, and protect against internal coolant migration that can compromise engine longevity.
