Installation Notes
  • The Edelbrock #8561 is made specifically for Pontiac V8
  • Installation is the same as for original equipment cylinder heads. Consult service manual for specific procedures, if necessary. For 389-455 engines, use Edelbrock #7381, Fel-Pro #1016 or equivalent head gaskets.
  • NOTE: Edelbrock Cylinder Head Gasket Set #7382 may also be used. This gasket set includes all necessary gaskets for cylinder head installation, including cylinder head, intake, exhaust, water neck and valve cover gaskets.
  • Be sure that the surface of the block and the surface of the head are thoroughly cleaned to remove any oily film before installation.
  • Use alcohol or lacquer thinner on a lint-free rag to clean. Coat threads, washers, and underside of bolt heads with motor oil for accurate torque readings.
  • Torque upper row of bolts to 105 ft. /lbs., torque lower row of bolts to 95 ft./lbs. in three even increments. Start in center and work out towards ends.
  • A re-torque is recommended after initial start-up and cool-down (allow 2-3 hours for adequate cooling).
