    These AHC small-block Chevy tight fit headers are the most universal steel tube headers available. These performance headers fit difficult applications where space is limited. They are a favorite for street rods, as well as many 1950's and 1960's cars and vintage trucks. These ceramic coated headers provide superior performance and durability.

    Tight Tuck headers are the solution to many problems associated with engine swaps in modern street rods. Tight Tucks fit in the tightest of engine compartments and clear all stock motor mounts. Most headers are manufactured from durable 16-gauge tubing and comes complete with gaskets, header bolts and collector reducers.

    • Most tight fit header applications require the use of Accel shorty spark plugs
    • Round port
    • Compact design
    • Will NOT fit angle plug heads
    • Includes reducers, gaskets and bolts
    • Armor Hot Coat finish

    These "rams horn" cast iron manifolds were patterned off the 1962-63 327 Corvette but are not OEM remanufactured manifolds. They feature the big 2-1/2" diameter outlets and have provisions to accept original alternator type brackets.

    These headers are copies of the original headers on the 62-63 Corvettes and can be used on almost any small block application. The cast in brackets are for the water tank on the drivers side and generator bracket on the passenger side. These can be cut off and smoothed per customers preference. These are a square port configuration with 1-5/8” top to bottom and also side to side. Compare to your head port size for compatibility.

    • 1962-63 327 Corvette

    Thermo Tec 12001 Hi-Heat Header Wrap Coating, Black
    (Part #70412001)
    x
                

    To finish off a clean and well-protected Exhaust Insulating Wrap application it is recommended to use the Hi-Heat Coating. The coating will protect the wrap from abrasion and harmful liquid spills. Extra resins and binders toughen the surface, extend the life of wrap by protecting it from friction, and seal the pores to minimize the penetration of harmful liquids.

    The coating also works excellent as a paint directy on metal surfaces.

    You absolutely will not believe the quality of these painted, full length headers. These Musclemaxx headers feature 3/8" thick laser cut flanges that give you a leak free seal. Nearly equal length step tube design just like the racers run gives you a wider powerband and more horsepower. The four bolt collecter flange is unique in that it needs to be used with the Dynatech® reducer cones. This gives you a leak free ball and socket connection that allows movement as the engine torques under acceleration.

    These full length, painted headers will bolt straight up to the Dynatech® MuscleMaxx dual exhaust kit.

    Fits: 1967-69 Camaro 

    NOTE: Reducer cones ARE included.
