Abstract: The dual valve lifter assembly has a dual valve lift with two hydraulic lash adjusters therein and a guide for orienting and preventing rotation of the dual valve lifter. The guide has four ledges and the dual valve lifter has four flats which mate with the four ledges. The flats and the ledges prevent the rotation of the lifter. One pair of flats and one pair of ledges are spaced the same while the other pair of flats and the other pair of ledges are spaced at a different distance than the first pair of flats and ledges. The difference in the spacing of the pairs of ledges and flats allows for correct orientation of the lifter when mating it with the guide.
