Moroso Chevrolet Big Block (w/Symmetrical Port/Stock Heads) Valve Cover -12An Fitting - Alum - Pair

Moroso aluminum valve covers for Chevrolet Big Block engines, specifically designed for those with symmetrical port stock heads. These valve covers come as a pair and include -12AN fittings, making them a solid choice for builders looking to set up a custom oiling system or crankcase evacuation setup. The aluminum construction offers a good balance of strength and weight savings over stock steel covers.

When you're working on a high-performance Big Block Chevy, managing crankcase pressure is crucial for engine health and power. These Moroso valve covers are built to accommodate that need, with the integrated -12AN fittings providing a direct port for vacuum pumps or breathers. The symmetrical port design ensures they will fit correctly on heads that feature this specific port layout, which is common on many factory and aftermarket performance heads for these engines. The aluminum material also dissipates heat well, which can be beneficial in demanding applications.

This pair of valve covers is a well-built component for your engine build. Ensure your cylinder heads have the symmetrical port configuration before ordering, as these are specific to that design. They are designed to fit right and provide the necessary ports for advanced engine management systems.
