Valley Covers & DOD Delete
BILLET LS VALLEY COVERS
GEN III & GEN IV OPTIONS FOR CUSTOM LS BUILDS
Finish the area beneath your intake manifold with a CVF Racing billet LS valley cover. CNC machined in the USA from 6061-T6 billet aluminum, these covers are available in Smooth or Pocketed designs with Polished, Stealth Black or C3 Ceramic Clear Coat finishes. Mounting hardware is included.
Select the correct engine-generation option for your build and review the knock sensor delete and sensor requirements. The Gen IV cover does not accept the factory oil pressure sensor and requires a compatible aftermarket sensor with a 1/8-inch NPT connection.
Choose Your LS Valley Cover Configuration
Gen III & Gen IV Fitment
Choose the generation option listed for your engine on the product page. On a swapped or rebuilt LS, identify the engine and components actually installed rather than relying on the vehicle's original year or model.
Smooth or Pocketed Billet Designs
Choose the appearance that suits your engine bay, then coordinate the finish with your valve covers and accessory drive. Both Smooth and Pocketed styles are offered through the valley cover's product options.
Plan Around Your Engine Modifications
For a knock sensor delete or DOD/AFM delete build, confirm the selected cover's role in your complete engine configuration. Review sensor connections, intake clearance and the other components required by your build before installation.

LS Valley Cover FAQs
What is an LS valley cover?
The valley cover, sometimes called a valley plate or valley pan cover, closes the area between the cylinder heads beneath the intake manifold. It is a separate component from the valve covers mounted on the cylinder heads.
Can I retain the factory oil pressure sensor?
The Gen IV version of CVF's billet valley cover does not accept the factory oil pressure sensor. It specifies an aftermarket sensor with a 1/8-inch NPT connection. Also confirm that the replacement sensor works with your gauges or engine-management setup.
Is a valley cover a complete DOD/AFM delete kit?
A valley cover is an individual component, not a complete engine-conversion package. Confirm the additional hardware and engine-management changes required for your specific DOD/AFM delete build with your engine builder or tuner.
Does the knock sensor delete cover retain the original valley-mounted sensors?
This product is listed as a knock sensor delete cover. Review the requirements for your engine's sensor arrangement and engine management before replacing a factory cover that accommodates valley-mounted knock sensors.
What comes with the valley cover?
The billet valley cover includes mounting hardware. Review the selected product's contents and application notes for any additional sealing components, sensors or fittings needed for your installation.
