INSTALLATION PROCEDURE: PLEASE READ CAREFULLY
LEFT SIDE
1.Disconnect the battery cable to prevent damage to the electrical systems.
2.Unbolt the stock headpipes (both sides) at the exhaust manifolds and remove from the vehicle.
3. Remove the stock exhaust manifold, spark plugs, oil filter, dipstick tube, and clutch linkage (if so equipped).
4. Starting from below, work the header up through the chassis into position over the exhaust ports.
5. Insert the gasket between the flange and head. Start the header bolts (most restricted first) and tighten evenly.
6. Replace the spark plugs, dipstick tube, and clutch linkage (if removed).
7. Replace the oil filter. Headers will only fit with a short-type filter. Older models will require the purchase of a screw-on adapter.
8. If the generator/alternator was mounted on the exhaust manifold, use the purchased bracket to remount. Use the1”long header bolts to attach the bracket.See Figure A.
NOTE:If the engine had a radiator reservoir canister mounted on the stock exhaust manifold, use the purchased bracket with 1” long header bolts in the front holes of the flange. Attach the canister to the bracket with the stock bolts.See Figure B.
9. If the air conditioning compressor was mounted on the head, purchase bracket to reinstall.
RIGHT SIDE
1.Remove the exhaust manifold and spark plugs. Pre-1962 models require starter removal also.
2.Starting from below, work the header up through the chassis into position over the exhaust ports.
3.Insert the gasket between the flange and the head. Start all header bolts (most restricted first).
4.If the starter was removed, replace it while the header is still loose.
5. Tighten all the header bolts evenly. Replace the spark plugs. Check the clearance between the ground cable and the R-4 pipe. Reroute, as needed.
6. If the generator/alternator was mounted on the exhaust manifold, purchasebracket to reinstall. Use 1” header bolts to attach the bracket.
7. If equipped with air conditioning and the compressor is mounted on the right side head, modify the stock bracket according to Figure C to remount the compressor.
NOTE:If the stock bracket is different from the one shown inFigure C, purchase bracket to remount the compressor.
8.To connect the collector to the headpipes, purchase a reducer kit.
NOTE:If equipped with an aluminum Powerglide automatic transmission, it may be necessary to cut the reducer and weld a sharp bend to it to clear the shift linkage (when it is in park). If further clearance is needed, dent the pipe slightly. SeeFigure D.
NOTE:If the vehicle had a smog air pump connected to the stock exhaust system, it will be necessary to fabricate a connector from a piece of 5/8” O.D. tubing and weld it to the collector (drill hole before welding). SeeFigure E. Cut the tubing (at a straight section) coming from the air pump. Connect this collector with a length (approx. 2”) of 5/8” neoprene hose. Secure with hose clamps. SeeFigure F.
9. Connect the battery, start the engine, and check for leaks. Be sure that all brake lines, fuel lines, and electrical wires have sufficient clearance. Reroute, as necessary.
10. When finished, give your car a test drive, checking carefully for any new noises. After several days of driving, retighten all the bolts.
