I would try contacting Mike at Kansas Kustoms (316)663-3256. He splits all the manifolds for the earlier generation 216-235-261 motors so he should be able to do the 250. If not, Tom Langdon sells an excellent pair of manifolds to fit the 194-230-250-292 motors. I have a set of these (unfortunately not installed yet) but have trial fitted them and they look good. He is at
www.stoveboltengineco.com. I know there are other members out there who are using them. Hopefully one of them will repy for you. Both of these fine gentleman advertise in the 12 Port News.
