Valve Cover Spacers - SBC 1.150in (Pair)

The B and B Performance Products Valve Cover Spacers for Small Block Chevy engines (1.150-inch height, sold as a pair) are essential components for builders tackling tight engine bay configurations or high-rise intake manifold installations. These spacers create clearance between the valve covers and cylinder head, solving a critical fitment problem that arises when upgrading to larger intake plenums, stroker engines, or custom fuel injection systems on SBC platforms. Whether you're working on a street machine, race application, or restomod project, proper valve cover spacing prevents interference issues that would otherwise require expensive redesigns or component compromises.

Manufactured by B and B Performance Products (MPN 63900), these 1.150-inch spacers maintain the structural integrity of your valve cover gasket seal while elevating covers away from obstructing components. The spacer height is precisely dimensioned to work with stock SBC gasket thickness and fastener geometry, ensuring zero compression loss at the gasket interface—critical for preventing oil seepage that compromises engine cleanliness and longevity. Cast or machined construction provides durability through thermal cycling and vibration, while the pair configuration (left and right) guarantees balanced, symmetrical installation across both cylinder banks.

SBC enthusiasts running modern high-rise manifolds, large carburetors, or compact engine bay hot rods will find these spacers indispensable for achieving proper fitment without sacrificing cooling airflow or serviceability. Installation is straightforward: simply position spacers between the cylinder head and valve cover, then reinstall fasteners at their original torque specifications. Compatible with all small block Chevy variants from 262 to 400 cubic inches, these spacers integrate seamlessly into both OEM and performance gasket systems, making them a trusted choice for engine shops and weekend warriors alike.
