Stud flathead

Set of rare NOS unmachined heads and an even rarer nos intake manifold made by “KONG” Jackson. They are for use with 24 stud flatheads. If you are unfamiliar with KONG heads they were made for use at bonneville. These have not had any machining done yet. The intake is 2 piece and has interchangeable tops for running multi carb setups or a blower plate. It comes with a 4 carb top plate. These came from the KONG estate
