6. Apply a THIN film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to header side of
the header gaskets and stick the gaskets to the header flanges. Masking tape can be
used to help hold the gasket to the header.
7.
Right Side:
1. Remove the bolt in back of the right side cylinder head holding the EGR tube
brace.
2. Remove the bolts on the intake manifold holding the EGR tube.
3. Loosen the nut holding the EGR tube to the intake manifold and remove the tube.
4. Remove the oil dipstick and tube.
5. Remove the exhaust manifold bolts and remove the manifold.
6. Replace the spark plugs finger tight so debris will not get into the cylinders while
cleaning the head surface. We recommend the use of a gasket scraper, wire
brush, and sanding block to adequately clean the surface.
7. After cleaning is complete remove the spark plugs again.
8. Apply a THIN film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to engine
side of the header gasket.
9. From above, install R/S header and gasket. Start header bolts.
10. Note: Some of the tubular spacers welded to the header flange may be used in
your application to hold accessories. If this is the case, re-use your stock exhaust
manifold bolts/studs. Those spacers not used may be removed and the supplied
bolts and lock washers used.
11. The EGR tube must be cut and a ¾” section removed and the tube rewelded for
proper fit. Heli-arc welding is recommended (see Fig. 1).
12. Start all remaining bolts, including the collector to exhaust bolts and install the
modified EGR tube. Do not tighten completely at this time.
8. Left Side:
1. Remove the serpentine belt.
2. Unbolt and remove the A/C compressor from the bracket.
3. Remove speed control and diverter valve assembly.
4. Loosen nut and remove air injection tube from the exhaust manifold.
5. Remove manifold bolts and remove manifold.
6. Replace the spark plugs finger tight so debris will not get into the cylinders while
cleaning the head surface. We recommend the use of a gasket scraper, wire
brush, and sanding block to adequately clean the surface.
7. After cleaning is complete remove the spark plugs again.
8. Apply a THIN film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to engine
side of the header gasket.
9. Install header and gasket from above. Start bolts (most restricted first) but do not
tighten completely at this time.
10. Reinstall air injection tube, speed control, and diverter valve assembly.
11. Reinstall A/C compressor and brace using stock hardware.
12. Start collector to exhaust system bolts using supplied hardware.
13. Tighten all fasteners on both sides evenly.
14. Replace spark plugs and wires on both sides. Replace serpentine belt.
