FAST's Die Cast Aluminum Valve Covers are designed both to perform and to create a matching package with the FAST EZ-EFI 2.0 and FAST Aluminum Air Cleaners. Branded with the FAST logo, these black-wrinkle powder coated valve covers are manufactured in the USA and offered for Small Block Chevy, Big Block Chevy and Small Block Ford applications. A tall height is designed to clear aftermarket valve trains, while rails on the sealing flange help locate the gasket (SBC only). The valve covers are perimeter- bolt style, and each kit includes breathers.
