Holley Muscle Series valve covers bring back the past. If you miss the look inspired by 1970's era GM factory L82/LT1/Z28 equipped engines, yearn no more. The Muscle Series fills your desire with the iconic finned design and retro styling cues. Plus, the cast aluminum construction, along with the fin design, creates strength and rigidity to offer years of leak-free performance. These pairs of standard height valve covers feature one with a twist-in oil fill knockout (cap included), and one with a recessed area to place the included adhesive-backed Holley emblem or any round emblem of your choice. Both have pre-installed internal oil baffles, and PCV grommets are included. You may choose from four finishes to best dress your small block. They say you can't go back. Obviously, they aren't aware of Holley Muscle Series valve covers.
