    Holley 241-135 Details

    Holley is pleased to introduce their Muscle Series Small Block Chevy valve covers inspired by 1970’s era GM factory L82/LT1/Z28 equipped engines. These valve covers are a continuation of Holley’s Vintage Series valve cover line featuring a classic finned design and retro styling cues. Each set consists of one valve cover with a twist-in oil fill knockout (oil fill cap included) and one with a recessed area to place an adhesive backed Holley emblem (also included) or any round emblem of your choice.

    Small Block Chevy "Muscle Series" Valve covers, Finned- Black Finish

    • Designed to fit all 1958-86 Small Block Chevy engines with perimeter bolt patterns
    • Die-Cast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks
