Edelbrock Intake Gaskets Chevrolet 348/409 Inwin for Small Port Cylinder Heads

The MP-2N Micropore technology in these Edelbrock intake manifold gaskets is designed to create a seal using less clamping force, which is a notable advantage when working with older engine blocks like those found in 1958-1965 Chevrolet W-Series 348 and 409 engines with small port cylinder heads. This synthetic fiber composite is impervious to most chemicals and offers high recovery under load, meaning it conforms well to sealing surfaces even if they aren't perfectly flat. This is crucial for achieving a reliable seal that lasts.

A nitrile bead around each port opening further enhances the seal, helping to prevent leaks and ensure optimal flow and performance from your intake manifold. These gaskets are matched to both the intake manifolds and cylinder heads they are designed for, simplifying installation and ensuring they fit right. This makes them a solid option for anyone rebuilding or working on the top end of these classic Chevrolet engines.
