Small Block Chevy
Cork-Lam Valve Cover Gasket
  • Chevy Small Block V8 262, 265, 267, 283, 302, 305, 307, 327, 350, 383, 400, and 400 Race
  • 4 Perimeter Bolt-Hole Design
  • .313 in. Cork-Rubber over Steel Core Adds Clearance
  • Pair

    Fel-Pro 1604 valve cover gaskets are built for Small Block Chevy V8 engines that see race-style crankcase vacuum, pressure spikes, and valve cover sealing stress. The Cork-Lam construction sandwiches a solid steel core between cork-rubber sealing faces, giving the gasket strength against blowout while helping maintain clamp load. At .313 in. thick, this pair also adds valvetrain-to-cover clearance, a useful detail for performance builds and tall aluminum valve covers.

    Fel-Pro 1604 Features:

    • Cork-Lam construction uses a solid steel core with cork-rubber material bonded to both sides for a stronger, more stable valve cover seal.
    • .313 in. thickness is greater than a typical valve cover gasket, helping retain torque and add clearance between the valvetrain and valve cover.
    • Engineered for high-vacuum and blowout conditions commonly found in racing and high-output Small Block Chevy applications.
    • 4 perimeter bolt-hole layout matches compatible Small Block Chevy valve cover designs.

    Includes:

    • Pair of valve cover gaskets

    Recommended for many performance builds using tall aluminum valve covers. Because the steel-core gasket is .313 in. thick, confirm clearance if the valve cover has a gasket retaining lip.

    Fits Small Block Chevy V8 applications in 262, 265, 267, 283, 302, 305, 307, 327, 350, 383, and 400 cu. in. displacements, including 400 race engines. Not intended for use on emission-controlled vehicles.

    • Cork-Rubber is the most frequently used material. FEL-PRO Blue Stripe premium-quality cork-rubber gaskets use evenly-sized cork particles evenly distributed throughout a rubber binder. The result is a compressible gasket without leak paths.

      Fel-CoPrene synthetic rubber can offer longer life than cork-rubber. However, because it is more flexible than cork-rubber, it can be more difficult to install. Generally, a quick-drying contact adhesive should be used to bond the gasket to the valve cover before installation.

      Rubber-Coated Fiber is used for some high heat applications, such as Chrysler big block V8 engines, where the valve cover is in close proximity to the exhaust manifold. These Fel-Pro gaskets are made of a stiff, high temperature fiber material coated with latex rubber.

      Cork-Lam is used in applications where high vacuum or blowout conditions can be a problem. Cork-Lam uses a metal core with cork-rubber material chemically bonded to it on both sides. This construction allows for a thicker than normal gasket with exceptionally good torque retention and also allows for more clearance between the valve cover and valvetrain.

      Composite Material is a superb choice for Pro-Stock, Funny Car/Dragster, and NASCAR race engines. Laminated over a steel core, the composite material offers maximum compression and torque retention in super-high vacuum conditions. The Fel-Pro gasket is also coated with silicone for even greater sealing and easier removal.

      Molded Silicone Rubber gaskets provide for ease of installation and are great for on again/off again situations like valve lash setting. These Fel-Pro gaskets feature high-tech silicone material for long life and sealing, a solid steel core for strength and durability, and stainless steel compression limiters to prevent overtightening. This is an excellent choice for high vacuum race engines.
