LT4 Engine Valve Covers for Corvette Z06, Camaro ZL1 and Cadillac CTS-V

Our custom valve covers are machined locally in Illinois and both powder coated/anodized for a pleasing finish. The idea here is to dress up the engine compartment and ideally pair the valve cover look with our aftermarket lid.

Engine Configuration and Compatibility
LT4 Lids designed for Wet Sump Engines. To fill a wet sump engine with oil use one of the 1/4-18 NPT holes for the PCV.

Additional Hardware Needed

  • 16 pcs. 1/4-28 x 1 1/4” under head length socket head cap screws to mount coils to coil brackets.
  • 8 pcs. 5/16-24 x 3/4” under head length socket head cap screws for mounting coil brackets to valve covers.
  • 2 pcs. Vivent 45 degree 1/4” NPT to 4AN fittings IF AND ONLY IF you plan on using the stock PCV lines.
