Engine Fitment

Designed for compatible GM Gen III and Gen IV LS engine configurations using a wet sump oil system.

Confirm cylinder head, ignition coil, ventilation, and engine compartment compatibility before ordering. The raised profile does not guarantee clearance with every aftermarket rocker arm or valve spring combination.

Coil Relocation & Finish Options

A compatible Katech Coil Relocation Kit positions the ignition coils above the valve covers to make the covers more visible. Select the kit that matches your engine and coil configuration.

This listing is for raw cast aluminum covers. Optional coating is available separately through the Katech Custom Valve Cover Powder Coating Service.
