This popular chrome valve cover came on many 427 engines in the 60’s, including most 427 and 428 powered cars that included the 427 Cobras, 7 liter Galaxies, R-code 427 Fairlanes, and numerous racing vehicles of the day. These will fit all 352-390-406-427 and 428 engines, and will clear most all aftermarket roller rocker setups. They are outfitted with no breather holes, just like the originals, so a fill tube in the intake manifold and or a working PCV system will be required. Original valve covers are very hard to find and rechroming them today will cost between $200.00-300.00. One pair.
