Product Details
If you're working on a Pontiac V8 engine from the late 60s through the late 70s, this Cometic Multi-Layer Steel (MLS) exhaust manifold gasket set is what you'll need to seal up those headers or manifolds. These gaskets are designed to handle the high heat of exhaust systems, rated up to 2000 degrees Fahrenheit, making them a solid choice for performance builds or just getting your classic back on the road.
What's neat about these Cometic gaskets is their compressible nature. Even if your manifold or cylinder head sealing surfaces aren't perfectly flat – which can happen with older engines – these gaskets can still conform and create a tight seal. This set features a split center port design with specific dimensions for the "D" port shape found on many Pontiac V8 exhaust ports, and they're precisely .030 inches thick to maintain proper compression ratios.
This gasket set fits a wide range of Pontiac V8s, including popular models like the Firebird, Grand Prix, and Catalina, as well as some Buick and Oldsmobile applications from 1975. Make sure to check the full fitment list to confirm compatibility with your specific vehicle.
