Finned aluminum valve covers for Chrysler HEMIs of 331, 354, and 392 cubic inches. They are a nice heavy wall casting and come machined to accept wiper seals that let you use you stock spark plug tubes. They also come with stainless steel washers and buttonhead bolts so you have nothing extra to buy. These valve covers are styled after the ones made by Fenton and Edmonds in the early 1950's so they have that great traditional look!
