Holley's new cast aluminum LS valve cover adapter plates offer an innovative way to add the vintage styling cues of a 1958-1986 Small Block Chevy perimeter bolt valve cover to your modern GM LS engine. These adapter plates feature an integrated oil fill and are pre-threaded for PCV ventilation fittings. Simply install the LS valve cover adapter plate onto your GM LS1, LS2, LS3, LS6, or LS7 engine to serve as your true valve cover, install the coil packs on top and route the wiring harness and spark plug wires into their designated locations, and use a perimeter bolt SBC valve cover of your choice to hide the unsightly coils without the need for any coil relocation and retention of all the benefits of OE style coil-on-plug mounting.
Features:
  • Constructed of Cast Aluminum
  • Available in three finishes (Natural Cast, Black Painted, and Polished Finish)
  • Includes all mounting hardware that allows mounting of three different generations of coil packs
Part # 241-362 is required to fill crankcase with oil when using these valve covers.
Installation Notes:
Part # 241-362 is required to fill crankcase with oil when using these valve covers.
