These sand cast aluminum valve covers feature raised CHEVROLET 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.
Interior is open, same as stock covers.

Installation on a 1950 Chevy Panel Van
Patrick installed these PML valve covers on his 1950 Chevy Panel Van. The engine is a 1958 Chevy 283 V8. He purchased the polish finish valve covers and customized them with paint across the center to match his van and updated engine compartment.

Installation on a 1956 Chevy 265 V8
Chuck installed these PML valve covers on his 1956 Chevy. The 265 engine is original with 62,000 miles.
Initially, the covers would not installed because the valve springs were hitting the inside of the covers. The valve spings closest to the bottom two holes rubbed on the indentations for the bolt holes. Grinding off some material made enough clearance. He also needed to grind a small notch next to the intake manifold. This may be specific to the 265 engines, which might have a different fit than the 283 engines that came out in 1957.
