Holley GM Licensed Valve Cover Muscle Series SBC Center Bolt Natural Small Block Chevrolet ZZ6/Vortec Emissions Provision Holley 241-290

Holley's new Gm Muscle Series accessories are the latest expansion to our officially licensed Gm product line. These die-cast aluminum valve covers and air cleaner kits were designed to have a no-frills, modern style with prominent raised Gm Chevrolet and Bowtie logos.

Intended as an alternative to the existing Gm ZZ6 accessories, Holley's Gm Muscle Series dress up accessories can be the perfect addition to your engine bay if you are searching for a subtly custom variation from the OEM options. All Gm Muscle Series accessories are available in four custom finishes: natural cast, polished, satin black, and factory orange (all finishes have machined Chevrolet and Bowtie logos aside from polished version).

The Small Block Chevy center bolt valve covers (designed to fit Vortec/ZZ4/ZZ5/ZZ6) feature a generous internal height for exceptional valve train clearance and include pre-installed internal baffling, polished mounting hardware, and oil fill / Pcv grommets (valve cover gaskets not included).

Features and Benefits:

• Features clean, modern styling with high definition Chevrolet and Bowtie logo Specifically designed for Gm ZZ6 engines, but will fit all Small Block Chevy applications with center bolt style cylinder heads (Vortec, ZZ4, ZZ5, ZZ6) - polished mounting hardware included Die-cast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks Emissions compliant valve covers include pre-installed internal oil baffles as well as an oil fill plug and Pcv grommet Offered in four unique finishes to fit your style: natural cast aluminum with machined logo (ready for custom paint), polished, satin black with machined logo, and factory orange with machined logo

Associated Comments:

• Notice: Natural finish parts are straight from the die cast tooling. These parts are intended to be brush finished, polished, painted, etc.
• prior to use. These parts will have some visual inconsistencies and tooling marks from the manufacturing process.
• These valve covers include mounting bolts and grommets for installation onto a ZZ6/Vortec Sbc head. Valve cover gaskets are not included with the set.
• Purchasing new valve cover gaskets is recommended, but not required - replacements may be necessary over time. Caution: If your engine has non-standard valve train components, such as a high-lift camshaft, roller-tip rocker arm, higher lift ratio rocker arms, stud girdles, etc., there may be insufficient clearance when using the Holley-Vintage Series
