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

Good product for face.
Great product. Works well with decreasing lines in face after half is used and with the serum. It does leave somewhat of a sticky (not grimy) texture which is uncomfortable if using at night.

Loose under eye skin tightened and brightened!
I love this cream! It makes a huge difference in the strength of the skin under my eyes and smooths the look and feel of the wrinkled skin under my eyes. It brightens my under eye circles. I gave 4 stars because if you use too much it will start to roll off almost like skin does when it sheds or when you exfoliate. I use less now and it’s perfect.

Working on Deep Wrinkles Great Results
I really like this product, it’s been working well on deeper wrinkles, especially on my forehead and around my smile lines. With consistent use, I can see a noticeable improvement in how my skin looks. The texture feels hydrating and smooth, and it absorbs nicely without feeling heavy. It leaves my skin feeling softer and more refreshed after each use. I also like that it helps with overall skin appearance, making it look more even and a bit more radiant. Minor note: Results take consistency, so it’s best to use it regularly to see the full effect. Overall, this is a great product for targeting fine lines and deeper wrinkles. Hydrating, easy to use, and delivers visible improvements over time.

Didn’t live up to the hype.
I had high hopes for this product. I’ve seen it all over social, but for me it didn’t live up to the hype. Although it is very moisturizing, it never dries down. There’s no way I could apply makeup over this, as the ads might lead you to believe. If you want a good night time moisturizer then this product is for you.

No Good
So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!
