Brighten up your Chevy Gen-IV LS with the Tick Performance Billet Valley cover. CNC-Machined in house from a single piece of aluminum, our billet valley cover offers a superior look, finish, and quality to your build. It arrives with o-ring gaskets pre-installed, so the cover is ready to bolt on. 

DOD Delete:

When upgrading to a Tick Performance cam kit with DOD delete, it’s necessary to replace the valley cover. Our billet valley cover offers o-ring gaskets to seal off each DOD lifter plug and a large o-ring gasket to seal the cover itself. The cover features no previsions for PVC. 


The cover is designed to fit all Gen IV LS engines with and without DOD.
