Product Details

Muscle™ Valve Covers (241-135) by Holley®. These new products are the 1st of the Vintage Series family of die-cast aluminum dress up products featuring a classically inspired finned design and a retro-style Holley script brand mark.

These valve covers were designed to add an additional 0.54” of internal clearance over factory height valve covers.
