1. Be sure that the mating surfaces of the block and the surface of the cylinder heads that will meet the valley
cover are thoroughly clean and free of any oils or debris before installation. Use alcohol or lacquer thinner
on a lint-free rag to clean.
2. Apply a continuous, 1/8” bead of automotive RTV silicone sealer to the end sealing surfaces on block and
along bottom of intake flange on the cylinder head where it will meet the valley cover.
3. Pay special attention to the corners of the cylinder heads where they meet the end seal surfaces (Use a
bit more silicone here).
4. Position the valley cover in place on the engine and install the supplied bolts.
5. Tighten bolts to 10-12 ft./lbs., starting in the center and working your way to the ends.
6. Place the intake manifold in position and torque manifold bolts to 25 ft. lbs., following the factory torque
sequence.
