thanks you for choosing
DOUG’S HEADERS, the best fitting, highest quality header on the market. In order
to realize the full potential of our good fit, please read and understand these instructions completely prior to starting work.
Check to make sure you received the proper parts for your application. The header number will be stamped on the engine
flange. If you are unsure you have received the proper parts call before you start work.
Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid ground and is supported
by adequate safety stands! Remember: Hot asphalt will not support most jack stands!
Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts, accidents that impact the
configuration of the frame, and/or the installation of different engines or aftermarket cylinder heads.
Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in process, the
appearance of the ceramic coating may be altered in certain areas. The protection characteristics and thermal barrier properties
of the coating is never compromised. It is recommended that a cast iron manifold or old set of headers be used for this process.
Notice: The coating of these headers can be marred or scratched during installation. If the header needs to be returned and is
damaged, you will be charged for recoat.
DISASSEMBLY
1. Disconnect the negative battery cable from the battery.
2. If a car lift is not available, raise the vehicle 2 feet or higher and support with adequate
safety stands. Make sure the vehicle is on a flat solid surface and is stable.
3. Remove the Stock Exhaust system and exhaust manifolds from the engine
4. Remove spark plug wires and spark plugs.
5. Remove the alternator.
6. The fenderwells have to be modified for this header to work. There is an illustration on
the next page outlining our suggestion for this modification. Carefully cut the inner
fender as suggested using a Plasma cutter, Cut Off Wheel or Reciprocating saw taking
care not to cut through any wiring or plumbing. Check both side of the Fenderwell
before cutting.
