Installation Notes:

The Edelbrock #8566 is made specifically for big block Ford V8
Use Edelbrock # 7314 or Fel-Pro #1018 head gasket or equivalent. NOTE: For Performer RPM 460 (Non-CJ) heads, Edelbrock Cylinder Head Gasket Set #7365 may also be used. This set includes all gaskets necessary for installation of Edelbrock cylinder heads; including intake, exhaust, cylinder head, water neck and valve cover gaskets. Follow the installation instructions for the head gasket. Be sure that the surface of the block and the surface of the cylinder head is thoroughly cleaned to remove any oily film before installation. Use alcohol or lacquer thinner on a lint-free rag to clean. Apply engine oil to the head bolt threads, washer, and bolt where it contacts the washer. The head bolt washers should be checked that they seat properly on the bolt under head, and not on the head bolt under head radius. Torque the head bolt 135 ft./lbs. in four steps following the factory tightening sequence. A re-torque is recommended after initial start-up and cool-down (allow 2-3 hours for adequate cooling). Install the intake manifold bolts lubricated with engine oil not exceeding 25 ft-lbs of torque when tightening. It is also good practice to lubricate the exhaust manifold/headers bolt threads with a small amount of anti-seize paste. Spark plugs should also be tightened to a maximum of 10 ft-lbs of torque with the spark plug thread lubricated with a small amount of anti-seize paste.
