bolts, otherwise header leaks will most assuredly occur and there is no warranty against
this.
5. Remove the starter.
6. Remove the clutch linkage (4 speed applications only).
7. Remove the motor mount bolt.
PASSENGER SIDE
1. Remove the spark plugs.
2. Same as the
driver’s side, cut the head pipe back at location of the collector and remove
the exhaust manifold. Some Engines only have 4 manifold bolts from the factory. It is highly
recommended that the other two bolt holes on each head be drilled and tapped for bolts,
otherwise header leaks will most assuredly occur and there is no warranty against this.
3. Remove the oil filter and filter adaptor.
4. Remove the dip stick tube (if applicable).
5. Replace the spark plugs finger tight (so debris will not get into the cylinders during the
cleaning operation).
6. Remove any gasket material or any carbon deposits that remain on the head surface. The
use of a gasket removal agent will ease the removal of any gasket material. We
recommend the use of a sharp gasket scraper to remove the bulk of the material and to
finish the operation with a sanding block to provide a clean flat sealing surface.
7. After cleaning is complete, remove the spark plugs again.
ASSEMBLY
PASSENGER SIDE (NOTE: MUST INSTALL PASSENGER SIDE FIRST)
1. Lift the engine approx. 1-2 inches to allow adequate room to install the header. Some motor
mounts have a safety tab located in the center of the mount and that will have to be
removed if there is any interference on the primary tube.
2. Place header into position and carefully let engine down. Be sure not to crush header while
doing this. Once engine is sitting completely down, replace and tighten motor mount bolt.
3. Slip the gasket into position and start all bolts. NOTE: Start the fourth-bolt-from-the-front on
the engine first. Once all the bolts are started, tighten them down evenly.
4. Replace the oil filter adaptor and filter using the new gasket supplied.
5. Replace the dip stick tube (If applicable).
DRIVER SIDE
1. On some vehicles, the brake Distribution Block, MAY interfere with the L4 header tube. If
this is the case, you will need to relocate the block and brake lines upward by about an inch
or so. Failure to do so will result in the header not fitting.
2. Install the header, slip the gasket into position and start all bolts. NOTE: Just like the
passenger side, start the fourth bolt from the front of the engine first. Once all bolts are
started, tighten them down evenly.
3. Replace starter. Battery cable must not make contact with any part of the header.
4. Replace the clutch linkage (4 speed applications only).
5. Reinstall the spark plugs.
6. Install the reducers and attach to the rest of your exhaust system.
7. Reattach the negative battery cable at the battery.
