No Leaker Headers™

No Leaker HeaderThe company that revolutionized the coating industry with HiPerCoat® now offers its own headers for the small block Chevy.  HPC’s No Leaker headers were designed for the discriminating builder who appreciates quality and low maintenance.

This unique header offers true 16-gauge steel with 1-5/8″ tube diameters. The single plane hydra-formed merge collector is constructed of .090″ wall thickness which allows for a maximum clearance in confined areas.  The collector connection is a tapered modular flange like O.E.M.’s have utilized for years. This ensures a “No-Leak” connection to the 2-1/4″ down pipe (included in the kit).  Thick 3/8″ laser cut flanges attach the header to the head. Headers come coated with our famous HiPerCoat® polished aluminum finish inside and out. Eight other colors are also available.  To complete the installation, premium HPC No Blow™ gaskets and HiPerCoat coated fasteners are included.  Downpipes with bungs for O2 fittings are also available for fuel injected engines.

Developed as a universal block hugger header, the No Leaker fits street rods from 1929 – 1941, many post-war cars and trucks using rack-and-pinion steering, 1955 – 1957 Chevys and Chevy II’s with rack-and-pinion conversions (Heidts, TCI), 1963 – 1967 C2 Corvettes, and Chevrolet small block engine swaps into Jeep CJ’s, TJ’s and YJ’s, and Toyota FJ-40’s.  No Leaker headers fit most angle plug heads (OEM and aftermarket) and are available for both standard and D-port small block Chevrolet heads.

No Leaker headers will fit the GM 350 HO and ZZ4 engines but will not fit the LS1 and LS6 350 engines.

In a header shoot-out, Chevy High Performance Magazine had this to say about HPC No Leaker headers in January 1999:

“Are they better than cast-iron manifolds?  In this case, the answer is a resounding yes since the HPC shorties made 29 more horsepower at the top.  Close to the bottom of the power band the shorties made 30 lb-ft more torque at 2,800 and then again came on strong in the upper- to midrange and top end of the power curve.”

“While our tests showed a 4-degree engine temperature drop over our OEM exhaust manifolds, we also noted an engine compartment temperature drop of nearly 45 degrees!”

HPC No Leaker headers carry a lifetime guarantee against rust and corrosion as well as material and workmanship defects.  For more information e-mail us at

No Blow™ Gaskets

HPC No Blow gaskets are made of premium flexible graphite mechanically bonded to a perforated metal core. This process provides a gasket that easily conforms to the mating surfaces of the cylinder head and header while providing extreme temperature capabilities.

When heated, HPC No Blow gaskets expand up to 5-times their cold thickness, keeping header bolts tight and sealing warped header flanges and imperfect mating surfaces.

No Blow gaskets are available for most American V8 engines as well as 3½”, 3″ and 2½” three-bolt collectors.

    Header Gaskets $25.00
    Collector Gaskets $12.00
