There are two different styles of carburetors used with this package. The 2 primary (center) carburetors can be identified by a “P” that is stamped into the bottom side of the metering block while the 4 secondary (front & rear) carburetors have no marking in this location. See Figure 2. 3) Pre-installation Checks Before installing this system, inspect all the components to ensure they are free of shipping or handling damage. Check that the throttle linkages move freely on all four carburetors. Sweep the linkages through their arcs of travel. 4) Installation a) Installing the Intake Manifold Make sure the intake manifold is clean and free of debris, especially in the intake runners, on the cylinder heads, and in the lifter valley. Using the RTV silicone supplied, apply a thin bead around each of the water jackets on the cylinder heads and on the ends of the valley. Then install the intake gaskets on each cylinder head. Apply a thin bead of RTV around the water jackets and also on the gasket. If the intake gasket that you are using is embossed with silicone already then adding the extra RTV around the ports is unnecessary. Install the rubber gaskets onto each end of the valley. Now you can install the intake manifold on the engine, taking care
