These sand cast aluminum valve covers feature raised CORVETTE script lettering and 7 fins. They have perimeter mounting with staggered or offset bolt holes for 1955 to early 1959 cylinder heads. The mid height design clears most roller rockers.

These valve covers do not have a provision for PCV, breather or oil fill because the original valve covers did not have a provision for PCV, breather or oil fill. This was done in the intake manifold.

The holes to mount the valve covers on the engine are about 8.8 inches apart (center to center) on the intake or inside edge and 10 inches a part on the exhaust or outside edge.

Please check dimensions in above link to verify clearance for your application.
