Tex, To answer your question, you could make a flat steel plate, like 1/4" thick, to bolt onto the bottom of the stock intake manifold heat transfer chamber. Then drill and tap two holes in the plate, to allow you to hook up two copper tubes to the two pipe plugs on the Fenton headers. This will allow for heat transfer.
If you have questions about this, email me your address, and I'll send you a diagram from the May/June 2001 issue of the Inliner's 12 Port News.
