Overview:

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:

  • 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

Get one!
Color: Peacock Blue, Color: Peacock Blue
Very nice IPad case. It fits really nicely. It took a while to get it setup because of how well it fits but it is well worth it. I love the he fact it uses magnets to position the screen instead of tracks. Stays in place while working instead of slipping throughout the day. I would and will recommend and buy again.

Works Perfectly for 2025 Apple iPad A16
Color: A-Navy Blue
I was super surprised that the entire case had protective plastic to keep it scratch free before use. I bought it under $20 which is a really reasonable price. I wanted a hard case that could be angled in any which way I needed. I wanted it to be able to be used on a desk, table, my lap, and even in bed. The one major thing that I looked for was it's front cover display to use be used as a stand. A lot of cases use the inside of the cover to be placed face down on surfaces, which in turn, collects debris and other unwanted nastiness. Rarely can you find something as simple as that on Amazon, ironically. I tried it on the table and the magnets are incredibly strong. I lifted up the entire iPad and the front cover stand stuck together. It takes a good amount of force to adjust. That was a massive surprise and major benefit of getting this case that wasn't advertised. I don't care too much for the Apple Pencil holder on the top and feel it's an unnecessary feature. I use my iPad as either an extended display for workflow or just to watch movies, play games, and surf the internet. One of the things I did was remove the screen protector which was super easy to do. I don't need it since I already have a screen protector installed. Installation was super easy and removing the protective plastic was satisfying. The rubber is malleable enough to where it feels sturdy, but it allows installation to be simple and easy. The frame is nice and thick, alongside the protective cover. I have full confidence that if I dropped my iPad, it will survive without issue. I'm not concerned about the color, but it looks as advertised in the photos. I bought the blue one because it was the cheapest one and it ironically matched my blue iPad. Overall, and excellent purchase for an excellent product!
