Description

Holley LS valve cover adapter plates offer an innovative way to add the vintage styling cues of a 1958-86 small block Chevy perimeter bolt valve cover to your modern GM LS engine. These cast aluminum adapter plates include hardware to mount three different generations of coil packs under the valve cover without the need of any coil relocation kit, and you retain all the benefits of OE-style coil-on-plug mounting. These adapter plates feature an integrated oil fill and are pre-threaded for PCV ventilation fittings.
