1. Fully clean all traces of old gasket material and sealant from all of sealing surfaces. Apply Edelbrock Gasgacinch to both
the head intake flange and back of gasket. Let dry and install gasket to head.
2. 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 and deterioration.
3. For ease of installation and a cleaner look, we recommend using Edelbrock Manifold Bolt and Washer Kit #8559.
•
Manifold Torque: Torque all bolts in the sequence shown to 25 ft-lbs.
•
Prep and Tuning for Power: Optimum cylinder head port opening size should be as close as possible to the size of the
gasket being used. Port-match the manifold exits .020" per side smaller than either the gasket being used or the cylinder
head port opening, whichever is smaller.
•
Courtesy Checks: After assembling the injectors, fuel rails, support brackets, throttle body, spacer (if needed), gaskets,
and air cleaner, make sure that the throttle linkage will freely rotate to the full open throttle position and back to the idle
position without rubbing or interfering with any of the neighboring components. Also, if applicable, make sure there will
be enough hood clearance after your air cleaner has been installed.
