Manufacturer of Billet Valve Cover Spacers. Made With Pride in Cochranton, Pennsylvania. From 6061 U.S.A. Produced Billet Aluminum! With Medice Manufacturing Valve Cover Spacers you no longer have to use tall valve covers to clear enhanced-performance valve train components. Utilize your factory valve cover (or any valve cover) and gain space for high performance valvetrain parts/components. Our GASKETLOK feature incorporates a relief cut in critical areas. This additional process causes the gasket material to become embedded into the spacer providing a tighter grip of the gasket against the spacer surface. Store-Em Engine Storage and Painting Kits also available From MediceMfg.com Laser Engraved License Plates, Car show Signs, and Ornaments.
