[quote=Joe H]You could install a stainless steel plate with only a small opening between the two manifolds. It would heat but still limit how much. I doubt it would over heat, the valves don't seal 100%, not even 75%, it directs the exhaust down and out more then seal off the intake.

That sounds like a good idea. Maybe I could drill a few holes - 3'8"? - in the plate. I'm looking for something that will heat up faster when the engine is cold than the plates that are made to circulate radiator coolant under the intake manifold. Do you think I would have to have some machining done to one or both manifolds (the thickness of the alum plate) so they would still align and seal to the head?
