Installation Notes
  • The Edelbrock #8513 Head Bolt kit is made specifically for Chrysler Gen III Hemi 5.7L, 6.1L, 6.2L, 6.4L; Clean and inspect all hardware and parts prior to installation, look for obvious defects or shipping damages. Be sure that the surface of the block is properly prepared and clean the surface of the head to remove any oily film before installation. Use alcohol or lacquer thinner on a lint-free rag to clean. Ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with an appropriate thread chaser. Install the provided 1/4" pipe plug into the threaded oil drain hole closest to the front of the engine. Warning: Pipe plug installation is required on both sides of the engine to avoid oil leakage and possible engine damage. Install the cylinder head(s) with gasket(s) and check for binding or misalignment. Screw bolts into the block HAND TIGHT ONLY.
