It's one head for a Ryan Falconer V-12 aircraft racing engine. They are used primarily for aircraft pylon racing but he will make you one for your car. The engines are custom built. V-12 part #1291. It's covered in the latest printing in Leo S. book on page 126. Ryan and his son Erik run the company and the are great guys and very helpful. His V-12 engine is based on 2 Chevy inline 6's so the bore spacing is the same. A complete head will run about $6k. It's nice that my blower will be on the passenger side so I can still see and the headers are on the driver side far away from my intake. This should help with charge temp. They do not bolt up.
