JIMS® has engineered a kit for Shovel owners that updates the top end oiling to EV style. Kit includes chrome plated, billet tappet blocks and special Powerglide® lifters, pushrods and roller rocker arms. Oil is fed through the lifters and pushrods directly to each rocker arm, instead of through the rocker boxes, for equal distribution. Eliminates the external oil lines. The tappets maintain oil pressure better, run quieter on any type of cam and lubrication is improved because oil is now pressurized through the points of contact.
