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.

• INTAKE GASKETS: Manifold runners as cast, will fit well with Fel-Pro #1298 intake gaskets. The gasket match to the ports and bolt holes may

vary, and should be adjusted for best fit to the ports.

• END SEAL CLEARANCE: Due to varying deck heights and/or valley widths, either from decking the block or milling the cylinder heads, the end

seal clearance should be checked. Lay the manifold on the engine with gaskets in place, and measure the clearance. There should be a minimum
of .060” between the block surface and the end seal surface of the manifold. You may need to machine the manifold flanges or end seal surface
to achieve optimum clearance.
