Abstract
The low profile valve lifter assembly has flats inside the bore of the outer housing and walls are formed and extended down from the plate of the guide such that the walls align with the flats of the bore to prevent rotation of the lifter with the guide. A groove and protuberance are provided in the flats and on the side wall of the guide in order to properly orient the lifter with the guide. The flats can be connected to form a pocket and the walls of the guide can be connected to form a sleeve that mates with the pocket.
