INSTALLATION INSTRUCTIONS
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)
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.
4)
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.
5)
WARNING:
There is no gasket support for the manifold on the four bolt holes which are numbered 5, 10, 11, and 16 in
Figure 1. Damage to the manifold will occur if these four bolts are over-tightened. Hand tighten them with a 6” box-
end wrench. Do not use a torque wrench. Torque all of the remaining manifold bolts in two steps by the sequence
shown in Figure 1 to 25 ft/lbs. For ease of installation, we recommend using Edelbrock Manifold Bolt & Washer Kit
#8564.
