NOTE: Please refer to Edelbrock Performer Series Carburetor Owner’s Manual for detailed tuning procedures. 1. Due to design, the fuel/air mixture and cylinder charging are very efficient with the CH-6B intake manifold. Generally speaking, the stock jetting for the recommended aftermarket carburetors will not need changing. Specific applications may show an increase in performance through further tuning. 2. Aftermarket distributor curve kits may be used with this intake manifold. 3. Use modified or high performance cylinder heads such as our Performer RPM. 4. The compression ratio should be at least 9.5 to 1 to work properly with Performer RPM camshafts. 5. Installation of aftermarket headers, camshafts or both may lean carburetor calibration. Should this occur, recalibrate with a richer jet INSTALLATION: 1. Use only recommended intake gaskets set when installing this intake manifold. 2. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 3. Use a factory style valley pan along with the recommended gaskets. 4. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. 5. Install the intake manifold and hold-down bolts. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.
