Review HOLLEY Performance Aluminum Valve Cover Set

The Holley 890012B Performance Valve Cover Set is a high-quality replacement option for your old and worn-out valve covers. This set is specifically designed for small-block Chevrolet engines and comes with two valve covers, two breather caps, and two gaskets.

The valve covers are crafted from heavy-duty aluminum, ensuring durability and strength.

The covers are designed with a large, open design that allows easy access to the engine components, making maintenance and installation a breeze.

The Holley Performance Valve Cover Set also features a unique design with integrated breather caps.

The caps are also designed to be easily removable for cleaning or replacement.

The gaskets included in the set are made from high-temperature, butyl rubber material. This material provides an excellent seal against oil leaks and can withstand the harsh conditions of the engine bay. The gaskets are also pre-molded to fit perfectly on the valve covers and engine surfaces, eliminating the need for time-consuming manual shaping.

Installing the Holley 890012B Performance Valve Cover Set is a straightforward process. The covers come with all necessary hardware for installation, and the gaskets are pre-installed on the covers for easy installation. The set also includes detailed instructions to guide you through the installation process.

In summary, the Holley 890012B Performance Valve Cover Set is a high-quality, durable, and functional replacement option for your old valve covers. Its heavy-duty aluminum construction, integrated breather caps, and high-temperature gaskets make it an excellent choice for performance enthusiasts and serious DIYers.
