I am wanting to put on an Offy 2X1 manifold and Fenton cast iron headers on my 292 in my 53. The Speedway picture of the manifold looks like it has heat riser provision, but I dont see how it would integrate with the Fentons. Has anyone here ever used t a similar arrangement, and how did you set it up? And what carbs would work on this? Thanks, Steve
