    Hooker Headers 2301HKR Details

    If you are lucky enough to have a GM small block crate motor with D-port heads (FastBurn, ZZ4, etc.) you will find that regular headers just don't work. These shorty headers were specifically designed for these heads. These tight-fit headers are ceramic coated headers that feature 1-5/8" primary tubes and 2-1/2" collectors with 2" reducers. Includes bolts and gaskets. The block hugger headers are designed to make difficult installations easy.

    • Collector exits parallel with the oil pan rail for maximum ground clearance
    • Made from lightweight & sturdy 18 gauge tubing
    • Tight-tuck design for narrow frame rails
