I think I heard somewhere that some KE heads also had the extra plumbing back into the exhaust port for getting rid of extra pollution causing gasses, may be this is relevant to what you need also, and stock 3K and 4K heads lack these couplings,
Just a thought guy's, your best bet in my opinion would be a 5K Head at least you can plug the pollution ports with threaded plugs if they are not needed, and being in the states they got all the pollution gear sent to them because they need it over there. he he
