Holley's latest addition to our officially licensed GM product line is the GM Muscle Series accessories. These die-cast aluminum valve covers and air cleaner kits showcase a no-frills, contemporary style accentuated by prominent raised GM "Chevrolet and Bowtie" logos. Created as an alternative to the existing GM ZZ6 accessories, the Holley GM Muscle Series dress-up accessories provide an understated yet custom variation from the OEM options, making them a perfect addition to your engine bay. Available in four custom finishes—natural cast, polished, satin black, and factory orange (with machined "Chevrolet and Bowtie" logos, except for the polished version).
The Small Block Chevy center bolt valve covers, tailored for Vortec/ZZ4/ZZ5/ZZ6 applications, boast a generous internal height for optimal valve train clearance.
