If you were a performance enthusiast looking for cylinder heads prior to 1987, your choices were limited to scrounging through junkyards, going to a dealership for OEM parts, or spending a small fortune on aftermarket aluminum racing heads. There was no in-between option. At this point, noted speed merchant Bill Mitchell and a skilled team of engineering and manufacturing personnel collaborated to develop an affordable cast iron head for the small block Chevrolet that delivered impressive performance gains. Their first offering, the World Products Dart II (now Sportsman II) cylinder 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.
