Racers who use the latest cylinder heads or want a unique look for their engines-or both-can now find quality, lightweight aluminum valve covers at an affordable price. These Moroso fabricated aluminum valve covers have thick billet rails for superior gasket sealing and resistance to warping. They mount through tubes welded directly to the valve covers-to help maintain gasket-rail flatness and prevent leaks. The covers feature a tall design that will clear all rocker combinations, as well as stud girdles.
