Installation Notes:

The Edelbrock #8554 is made specifically for big block Chevy with Victor level cylinder heads
Installation is the same as for original equipment cylinder heads. Consult service manual for specific procedures, if necessary. For 454 CID and small Mark IV engines, use Fel-Pro head gasket #1017-1, or equivalent. For 502 CID Mark V and Gen VI engines, use Fel-Pro head gasket #1047, or equivalent. 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. Apply oil or suitable thread lubricant to head bolt threads and the underside of bolt heads and washers to prevent galling and improper torque readings. Apply liquid Teflon PST or other suitable thread sealant on any bolt threads that go into coolant passages. Torque bolts to 70 ft./lbs., following the factory tightening sequence (See Figure 1). A re-torque is recommended after the initial star-up and cool-down (allow 2-3 hours for adequate cooling).
