Valve Cover Gasket Set for 1958-1965 Chevrolet 348 and 409, 5/16 in. Thick
W-series 348 and 409 engines use a thick valve cover gasket, and the 5/16 in. dimension is not interchangeable with a small-block item. Core-reinforced composite holds its shape under clamp load instead of extruding out of the joint the way plain cork does after a few heat cycles.

- Two piece set, core-reinforced composite, gray.
- 5/16 in. thickness, six mounting holes.
- Fits Chevrolet 348 and 409 engines, covering 1958-1962.
- Gasket sealant is not included.
- Oil fill plug grommet and hold down tabs are not included.

This unique core-reinforced construction has a radial strength to resist high-vacuum or blow-out conditions.
