PML designed these valve covers for the classic hot rods of the 1950s and 1960s with the 348 or 409 Chevy™ W block engine. The clean design works well in restorations and vehicles where script or fins is not desired.
Benefits:
- Plain top for customization or clean appearance
- Heavy duty sand-cast aluminum construction
- Thick walls for strength
- Gasket flange will not bend or flex when bolts are tightened for a secure seal
- Mounting hardware included
Some customers engrave or put a their own custom design on the top. Because PML valve covers have thick walls, the top surface is suitable for this. PML does not offer customization.
