Download 1. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 2. Apply Edelbrock Gasgacinch sealant PN 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. (Refer to instructions on Gasgacinch can for further reference). If you are using two-piece gaskets with a seperate tray, the valley pan will contact the cylinder heads with the gaskets resting on top. Both sides of the gaskets and pan should be coated with a layer of Gasgacinch. 3. Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼” high bead across each block end seal surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage. 4. Install the intake manifold and the intake manifold bolts with hardened steel washers between the manifold and the bolt heads. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.  PREP AND TUNING FOR POWER: 1. The long equal length runners in these manifolds create a very even air/fuel mixture distribution. In general, the stock jetting in the recommended carburetor will not need changing. Refer to your carburetor owner’s manual for details. 2. Performer manifolds deliver excellent drivability and power utilizing stock distributor settings. Some applications may benefit from resetting the initial advance ±2° from the factory specification.
