H8017 Full Length Header
Product Information
The product is a set of headers designed for use with small
block Chevrolet engines in street rods. The product is available in
three different models: H8017, H8018, and H8039. The headers are
made to fit the exhaust flange gasket surface of the cylinder heads
and come with a set of header gaskets, header bolts, collector
gaskets, collector bolts, and reducers. The product also comes with
a warranty.
Product Usage Instructions
- Before installing the headers, remove and mark all spark plug
wires and then remove all spark plugs. Remove the oil dipstick
tube. - If the generator/alternator or air conditioning is mounted to
the exhaust manifold, remove them now. - If you currently have exhaust manifolds or headers, remove them
from the vehicle. Remove the existing exhaust system. - If you have Vega Steering, Rack & Pinion or similar, remove
the steering shaft. - Clean the exhaust flange gasket surface of the cylinder
heads. - Install the headers (usually from the bottom of the vehicle,
depending on the header style and vehicle model). Slide the headers
into place and install a bolt at either end of the header to hold
them in place. This will allow you to determine proper fit. - You may need to remove clutch linkage, shift linkage, and the
starter depending on your vehicle. - Once you are satisfied that the headers fit your application,
install the gasket and the remaining bolts. Tighten all bolts
evenly working from the center out. - Reinstall the oil dipstick, generator/alternator (you may need
an H7606 bracket) and air conditioning. - Reinstall the steering shaft making sure it does not interfere
with the headers. If it does, you may need to add another U-joint
and a support bearing. - If you removed the clutch linkage, shift linkage, starter,
etc., reinstall them now. - Install the reducers and determine the connection to the
exhaust system. - Weld the reducers to the exhaust system and install them onto
the headers utilizing the gaskets and bolts supplied. - Install spark plugs and connect the wires to the proper
plug. - Check to make sure that all the wiring, brake lines, hoses,
etc. are clear of the headers or any exhaust component. - Connect the battery cables.
