Fel-Pro 1638 is a performance valve cover gasket pair built to seal Buick-Dart race cylinder heads on small block Chevy engines. The rubber-coated fiber construction and .094 in. thickness support high-heat use where the valve cover sits close to the exhaust manifold, helping performance and high-horsepower builds address sealing demands without relying on generic replacement gaskets.

Fel-Pro 1638 Technical Specifications:

Rubber-coated fiber material is specified for high-heat valve cover locations near the exhaust manifold.
.094 in. gasket thickness provides a defined sealing profile for the intended race cylinder head application.
Designed exclusively for Buick-Dart race cylinder heads used on small block Chevy engines.
Performance application gasket construction is suited to high-horsepower engines and difficult sealing surfaces.

Includes:

Pair of valve cover gaskets

Use for performance engine builds that place the valve cover close to exhaust heat and require a purpose-built sealing material for race cylinder heads.

This gasket set is for Buick-Dart race cylinder heads on small block Chevy engines and is not intended for 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.
