Review HOLLEY Aluminum Valve Cover Set

The Holley 890012 Valve Cover Set is a high-performance upgrade for your engine, designed to provide superior sealing and protection against oil leaks and contamination. This set includes two valve covers, one for each bank of cylinders, and all necessary hardware for installation.

The valve covers are made from high-quality aluminum, which is lighter than traditional cast iron covers and helps to reduce engine heat. The aluminum construction also allows for superior cooling, reducing the risk of oil thinning and breakdown. The Holley valve covers feature raised edges and deep gaskets, ensuring a tight seal and preventing oil leaks.

Each valve cover is equipped with a breather system, which allows for proper crankcase ventilation while maintaining oil seals. The covers also come with pre-installed PCV valves, making installation even easier. The PCV valves help to control crankcase pressure and reduce emissions.

The surface of the Holley valve covers is CNC machined for a smooth, flat finish. This ensures a perfect fit and eliminates the need for time-consuming and messy sanding or grinding during installation. The covers are also designed with factory-style mounting bosses, allowing for easy integration with factory or aftermarket accessories.

The Holley 890012 Valve Cover Set is a great choice for performance enthusiasts looking to upgrade their engine with high-quality, leak-free components. The set is compatible with most small-block Chevrolet and GM applications, including those with hydraulic roller camshafts and solid lifters. With its superior sealing, cooling, and ventilation features, this valve cover set is sure to provide improved performance and reliability for your engine.
