Our Phathead Racing cylinder heads work great with big bore cylinder applications. They provide additional cooling capacity and make tuning easier by allowing fast and inexpensive compression ratio changes due to our interchangeable dome design. We can custom modify stock domes for any bore size within the limits listed for each dome family. Call Lukes Racing/Phathead Racing (734) 648-0103 about a custom big bore/stroker build today.  We stock  supermini kits and domes to match!
