[More Info]
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.
Features:
  • 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
  • Standard height valve cover with pre-installed internal oil baffles
  • Factory style twist-in oil fill cap, round Holley emblem, and square oil fill and PCV grommets included
  • Available in four finishes to best suit your custom build: natural, polished, gloss black, factory orange
These cast aluminum valves covers these may be slightly taller than OEM, however they are not designed to work with roller style rocker arms.
Installation Notes:
