These brushed Hamburger's fabricated aluminum valve covers are for use on 1959-79 326-455 Pontiac engines. They are super strong, yet very lightweight. They are precision manufactured using 1/4" rails to provide a positive seal and eliminate oil leakage between the valve cover and head. This pair of valve covers has no breather holes, allowing you to locate them as your situation requires. They measure 3-11/16" tall and have a great looking brushed aluminum finish that is easy to maintain. This set includes mounting hardware, but gaskets are sold separately.
