    These cylinder heads are designed exclusively for the SCCA American Sedan Series Class. To comply with class rules, there is no blending work in the intake entries, exhaust exits or bowl area of the intake or exhaust. Bare cylinder heads will require final sizing of the valve guides and a proper valve job prior to the installation of valves. These heads are engraved with a SCCA approved logo and legal for American Sedan Class.

    Installation Notes:
  • 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.
  • Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat.
  • This head does not include valve springs due to the wide variety of camshafts used in competition.
  • Deck thickness: 9/16
  • Rocker stud diameter: 3/8"
  • Pushrod diameter: 5/16" (width of slot in guide plate).

    These heads are based on the popular RPM series of cylinder heads for S/B Chevy and Ford. They are exclusively designed for the SCCA American Sedan Series Class

    All heads feature smaller intake valves, exhaust valves and non-interlocking exhaust seats. Manufactured from A356 aluminum and heat treated to T6 spec for superior quality and supplied with Manganese bronze valve guides, Heli-Coil® inserts in the exhaust and rocker stud holes. Bare heads are supplied with reamed and semi-finished valve stem guides and no valve job. Final guide sizing and valve seat finishing must be completed before installation.

    Engraved with the SCCA logo on both ends to help verify legality. These new cylinder heads have been approved by the SCCA for American Sedan Class competition. Made In The USA!
