Holley is pleased to introduce a finish expansion to our popular Tall LS valve cover lineup. Previously only available in Natural Cast, Satin Black, Gloss Red and Polished finishes – the full lineup of Holley Tall LS valve covers is now available in our increasingly popular Factory Orange finish. Each of these Tall LS valve cover sets were designed to add an additional 0.54" of internal clearance over factory height LS valve covers.

These valve 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 (not included with Dry Sump version, P/N 241-99).
