Oldsmobile Billet Valve Cover Spacers for Gen2 V8's
Clearance Without Compromise.
When you’re building a high-performance Oldsmobile, the valvetrain often outgrows the factory footprint. High-lift cams and roller rockers require extra room, but you shouldn't have to sacrifice your preferred valve covers or settle for stacked, leaky gaskets. The Performance Driven Design Billet Valve Cover Spacers provide the necessary vertical clearance while maintaining the structural integrity of a solid-mounted system.
The Solution for High-Lift Valvetrains.
These spacers are the "missing link" for enthusiasts running aggressive valvetrain setups. By precision-machining these from 6061-T651 Aluminum, we provide a perfectly flat, rigid extension of your cylinder head. Unlike plastic or wood spacers that can warp and cause catastrophic oil leaks, our billet spacers expand and contract at a rate consistent with your engine, ensuring a permanent seal.
Precision Alignment. Effortless Install.
True to the PDD "True DIY" philosophy, these spacers are machined to exact OEM tolerances. They align perfectly with your bolt holes and cylinder head rails, providing a rock-solid foundation for your valve covers. It’s the professional way to gain clearance without resorting to "tall" covers that might interfere with power boosters or AC boxes.
