Wanted Hudson 7x 232 head

Hello,

I currently am trying to build a correct hudson 7x 308. I know I can get any 232 head done to meet the 7x spec but it would be nicer to find a real 7x head if there are any still out there. I’ve already acquired the exhaust manifold and twin exhaust portion as well as a factory 7x block and almost new 7x camshafts. I also have some crankshafts Smokey yunick tampered with so that may go in too. Any leads would be nice!
