Info

Direct bolt-on heads for Big Block Ford Stock and Super Stock racers. No port profiling or bowl blending of ports. Engraved with the NHRA Logo on both ends.

  • Thicker Deck Surfaces than Other Brands

Notes

NHRA legal for Super Stock only. Also designed for SVO 514 cu. engines. 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. Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4"" reach with flat gasket seat.
Some parts are not legal for use in California or other states with similar laws/regulations
