***Note: As of 6/4/24 these valve covers come with ball milled surface***

Motion Raceworks seeks to innovate their way into simplifying builds while focusing on aesthetics and overall function! These billet LS1 valve covers are a showcase and a prime example of this.  

The result is a valve cover that is something that can be used for a HUGE variety of builds without sacrificing looks or function.

A variety of factors go into keeping coil packs on the valve cover including looks, serviceability, coil choice, clearance for fittings, header design, and more.  Whether you choose to run coils or not, this cover is perfect for you.  Featuring a top rail mounting design, if you do not wish to run coils, there are no leftover mounting bosses or holes that are unsightly or in plain view.  If you decide to run coil packs, every LS coil made as well as aftermarket coils such as Smart Coils (IGN1A), CDI can be used.  We thought of everything. To add the brackets, you simply choose the bracket options in the listing or add ala carte at a later time.  

Every coil bracket is adjustable and clears not only the breather fittings, but also allows for a large billet oil cap. Finally valve cover hardware to remove valve cover is accessible and usable with coils on the car.  

Additionally, coil packs have been checked and will clear intakes, fuel rails, and even wide hanging superchargers.  


At Motion Raceworks we understand PCV and crank case pressure is unavoidable.  We also believe that filling catch cans up with oil due to poor breather design is not acceptable.  This valve cover features a long high flow breather channel which will remove excess crank case pressure, and is serviceable by removing C-Clips. Our cover was machined on the top side to receive one of our custom low profile -12 ORB fittings.  This means you can adapt to 10AN or 12AN. 

Note: Custom fittings were designed and made to allow for packaging and clearance of internal baffling, standard -12ORB fittings will not work.  Fittings Included, but also sold separately.
