Description

These adapter plates feature an integrated oil fill and are pre-threaded for PCV ventilation fittings. They allow installation of LS style valve covers onto GM LS1, LS2, LS3, LS6, or LS7 engines, serving as the true valve cover. Coil packs can be installed on top, with wiring routed to designated locations. They also allow using perimeter bolt SBC valve covers to hide coils without relocation, retaining OE style coil-on-plug mounting.
