Intake Manifold: Installation

  1. Apply suitable oil resistant sealer at four junction points of seals and gaskets. Position front and rear seals on cylinder block and new gaskets on heads. Make sure that holes in gaskets are aligned with holes in cylinder head.
  2. Position gaskets so interlocked with seal tabs. Lower manifold on engine and check for correct positioning of gaskets and seals before installing bolts. Install bolts and tighten to specifications.
  3. On 351" M and 400" engines only, run engine until normal operating temperature is obtained, then retorque bolts.
