you can also buy a "heat riser block" to get rid of it. it looks identical to your heat riser but has no butterfly in it. it will take longer for the truck to warm up since you are not forcing heat through the crossover in the intake BUT you never have to worry about the butterfly becoming frozen in the closed position.
