Ansen USA valve covers and air cleaner lids are built from high-grade die-cast aluminum and proudly Made in the USA. This kit starts off with a set of Small Block Chevy Tall valve covers with raised letter 383 STROKER logo and red powder coat finish. The 15" oval lid features a 383 STROKER die-cast raised logo and racing fins. Each air cleaner lid is individually made, 1/2" thick, weighs a hefty 3–1/2 lbs, and built to exact specifications. Once our lids are die-cast and processed, red powder coat is applied on the entire lid. Then, they're given a line grain finish. Must see to fully appreciate. Fits single carburetor set-ups and comes with all necessary hardware to mount. The kit features an air filter element, red base mount, and mounting rod.
