For sale is a beautiful set of 1967 Mustang 289 Hi-Po K-code cylinder heads. Date stamped “6M22” for your early 67’ Mustang or Shelby. The thermactor threads are currently plugged but can be easily removed to go back to its original thermactor system. The heads will need a spring, valve, stud kit. Very clean and smooth surfaces, dry stored. I would not hesitate to use these on a high-end build or restoration. Can provide additional pictures or FaceTime as needed. Would prefer local pickup in Wendell, Idaho but can ship insured and package well at buyers expense.
