Holley's Dominator valve covers are the newest addition to our ever expanding line of products specifically designed for LS engines. Based on our existing tall LS valve covers, the new Dominator valve covers eliminate the coil-on-cover look and instead feature bold graphics that can represent your loyalty to the Holley brand and intimidate the competition. As a tall LS valve cover we have added an additional 0.54" of internal clearance over factory height valve covers, which allows for additional valve train clearance and adds a muscular touch to your engine bay. The Holley Dominator valve covers are designed to fit LS1, LS2, LS3, LS6 and LS7 engines. These covers come ready for installation with an OE style baffle and ventilation system, lengthened factory style mounting hardware, and a billet aluminum oil fill cap.
