LS1 Valve Cover Spacers (Pair)

The YELLA TERRA LS1 Valve Cover Spacers are precision-engineered lift blocks designed to create clearance between your LS1 cylinder head and valve covers, addressing common fitment challenges in LS swap installations and modified engine builds. These spacers are essential for those looking to install high-rise intake manifolds or upgrade ignition components while maintaining optimal engine aesthetics.

Manufactured from durable cast material with precision-machined contact surfaces, the LS1 Valve Cover Spacers ensure factory-level sealing performance while providing the necessary vertical clearance for problem-free installation. They come complete with all necessary hardware and gasket surfaces, which helps eliminate oil weeping at the cover-to-head junction, a critical concern when modifying engine layouts.

Mechanics and enthusiasts performing LS engine swaps or big-inch builds will find these spacers invaluable for resolving fitment conflicts without costly fabrication or engine repositioning. Installation is straightforward—remove stock covers, install spacers with new gaskets, and reinstall covers using extended fasteners—making this modification accessible for DIYers and professionals alike.
