Description

Holley Muscle Series valve covers are a blast from the past inspired by 1970s-era GM factory L82/LT1/Z28-equipped engines. They fill your desire with the iconic finned design and retro styling cues. You can choose from four finishes to best match your small block. Order the pair recommended for your year/make and engine application.

Product features include:

* Cast aluminum construction and fin design create strength and rigidity to offer years of leak-free performance
* Standard height
* Twist-in oil fill knockout (cap included) on one cover
* Recessed area to place the included adhesive-backed Holley emblem or any round emblem of your choice on the other cover
* Pre-installed internal oil baffles on both covers
* PCV grommets
