    Vintage style street rods are hotter than ever, and nothing gives your fenderless rod an authentic dry lakes competition look like a set of lakester headers. These lake style header kits allow you to build your own headers and tailor them to your vehicle. All tubing comes pre-bent. Tapered cones can be trimmed as needed. Lakester header kit includes parts to complete both sides.

    • 5/16" thick flanges
    • 16 ga. pre-bent tubing
    • Collector flanges w/ block-off plates
    • Flanges for connecting an under-car exhaust system (2.5" O.D.)
    • Gaskets & bolts
  • Big Block Chevy Fenderwell Headers for 1955-57 Chevy, Black
    Big Block Chevy Fenderwell Headers for 1955-57 Chevy, Black
    x
                

    These fender well headers provide the ultimate performance for 396-502 big block Chevy V8s in 1955-57 Chevy car applications. They kick up over the frame rail and exit just at the bottom of the cowl, which makes them perfect for Gasser-style rods and drag cars. Plus, these headers feature long primary tubes that help produce more horsepower and torque than shorter, more compact headers.

    These headers are not for the faint of heart since you must cut the inner fender panels to make them fit, and tire clearance can be a problem on some applications. They may require smaller front tires to avoid contact. The stock emergency brake rod must also be altered. Can be used with most oil filter systems or transmission and starter combinations. The headers are designed to be used with engines in the stock location, not lowered as many kits do, so all '55-'57 cars should check motor mount positioning before ordering.

    • Header flange has 1-13/16” x 1-13/16" port size
    • Will require fender well cutting or alteration
    • High temp black paint finish
    • Includes bolts and gaskets
    • Note: This header actually goes upward from the head instead of down before dropping over the frame rails. From the top of the head flange to the top of the tubes is approximately 9-1/2".

    You just bought your LS and plan on using the factory exhaust manifolds, but noticed they have odd shaped collector flanges. Now what? These flanges bolt to the factory factory manifold and allow for a smooth installation. Flanges are 3/8" thick.

    Specify driver or passenger side.
