Aluminum & Iron Cylinder HeadsA High-Performance Tradition 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 30-70 HP over stock heads. That same know-how went into Bill Mitchell Products’ entire line of Aluminum Small & Big Block Chevy Heads, LS & Ford Windsor Heads. They are available bare or assembled for many different engine builds. Save time and money and order them unassembled.
