Installation Notes
  • Match with Edelbrock head gasket sets.
  • Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.
  • To use stock rockers on small-block Chevy heads, .100" longer than stock pushrods are required. Edelbrock pushrods #9629 are recommended.
  • Use Head Bolt Kits for easy installation. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat.
  • S/B Chevy heads may not be used on engines with less than 4" bore (262, 265, 283, 305, 307 c.i.d.) except with cams having less than .450" valve lift.
