No Leaker Headers™
The 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
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
“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
|“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!”
