SPECIAL INSTRUCTIONS: CAUTION: Due to head casting differences at the upper four bolt holes, there may be a casting interference
between the manifold and the head. It may be necessary to file manifold for proper clearance to allow manifold to seat properly at the head
surfaces.

FIRING ORDER AND CYLINDER NUMBERING: For cylinder and firing order, see Figure #2.

FINAL TUNING
NOTE: Local emission laws must be checked for legality of any carburetor or ignition changes.
1.
2.
Minor changes may be made for final gains in performance and emissions depending on individual application, driving habits, engine condition
and vehicle use. Best results must be determined by the individual for his specific application.
3.
Due to the broad rpm range of this manifold, it is suggested that a basic ignition curve of 12° to 14° initial and a total of 36Þ to 38Þ advance
be used and then be tailored to your vehicle's needs.

CAMSHAFT AND RELATED PARTS: To get maximum performance with the Torker II manifold, we suggest using the Torker Plus camshaft
and matching components such as: Torker-Plus Camshaft / Lifters / Lube #5062, Sure Seat Valve Springs, #5762, Performer-Link True Rolling
Timing Set, #7810.
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.
