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. Some models have built-in oilers to keep valve springs cooler in oval track racing. Order the model designed for your vehicle and engine application.

Moroso PCV air/oil separators will help increase your engine's performance. These air/oil separators will capture excess oil and keep it out of your intake tract so that your engine will breathe cleaner intake air--better air equals better performance. Moroso offers universal and custom fit versions in small and large body sizes. The large bodies, besides having more capacity, feature a bottom drain with an elbow that makes draining the collected oil virtually mess-free. Their polished billet aluminum bodies can be chromed, painted, or powdercoated. The small units offer a 2-piece body that unscrews for draining and are available raw or with polished or anodized finishes.

Designed to shield your intake manifold from hot oil splash to maintain a cooler intake charge for more power, Moroso Lifter Valley oil baffles also help keep excess oil out of your valve covers and maintain oil pressure in the event of pushrod or rocker arm failure by keeping the lifters in their bores. Due to slight variations in blocks, the baffle may need slight trimming before they will "snap" into place.

Moroso offset cylinder head dowels reposition the cylinder heads upwards on the block toward the lifter valley. This moves the valves away from the cylinder wall for improved intake flow.
