hydraulic lifter update kit for Shovel. Evo oiling

This kit is basically the same set-up that S&S uses in their SH-series 'Shovelhead' engines. It enables you to upgrade your Shovelhead to the more modern Evo style valve train. Kit includes S&S Evo style tappets, billet aluminum CNC machined tappet guides, adjustable Quickee pushrods that are drilled for 'through the pushrod Evo style top-end oiling'. This top-end oiling requires the use of S&S 512493 roller rocker arm kit. Also included are gaskets, hardware and pushrod cover keepers.
