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. Install the intake manifold and hold-down bolts, following the torque sequence shown below.

Manifold #7138 should use the tightening sequence in the ovals
on the right. Snug all bolts initially, then tighten to 11 ft/lbs.
Use 30W motor oil on all threads.
Manifold #7137 should use the tightening sequence in the
boxes on the left. Tighten to 10 ft/lbs initially, and a final value
of 20 ft/lbs. Bolts installed in locations 1 -4 will often break
into oil and should have thread sealant applied to prevent
leaks. Use 30W motor oil on the other bolts.
