INSTALLATION NOTES—The area of the manifold above each pair of runners has been machined to clear the valve covers when used with most

aftermarket (aluminum) cylinder heads, such as Edelbrock Victor Jr. heads #7700. Can be used as reference point for port match. Additional manifold-

to-valve cover clearance will be required when manifold is used on most stock type (cast iron) heads. This may be accomplished by using extra-thick

valve cover gaskets or by trimming the manifold or valve covers as required. The manifold bolt holes have been slotted .100" up and down to allow

the manifold to work with competition engines which may have had the block or heads machined.

NOTE: With some cast iron cylinder heads, the bottom of the slot may not be sealed by the gasket, resulting in an oil leak from the valley area.

If this occurs, apply a small amount of RTV silicone sealant into the affected area to seal the leak.

1. Make sure the cylinder head intake flanges and the engine block end seal surfaces are fully cleaned prior to installation.

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.

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 hold-down bolts. Torque the manifold bolts to 25 ft/lbs in small, even steps, following the factory

recommended torque sequence

(See Figure 3)

. If you cannot fit a torque wrench on some of the bolts, use a small box end wrench to

avoid over tightening.

NOTE: Check bolt clearance near the water crossover. Minimal clearancing of the water crossover may be required for socket

or wrench clearance with a standard hex bolt.
