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.
