World Products® has been producing affordable high performance cast iron engine blocks and cylinder heads for twenty five years, beginning in 1987 with a pioneering small block Chevrolet cylinder head and continually expanding the line to become a leading aftermarket manufacturer. World Products first design was a cast iron head for the small block Chevrolet that delivered impressive performance gains. This head became an instant success and was named Product of the Year in 1988 by Hot Rod Magazine. It produces 30-70 HP over stock heads, and remains the only high performance cast iron small block head to be certified for use in many racing leagues.
