General product notes:

Note: Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs, Feuling highly recommends running one-piece pushrods (B962-09280091) over quick-install adjustable pushrods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.

Note: Feuling fastener kit B962-24010994 also highly recommended to help prevent cylinder head cracking, kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress of the rocker shaft standoffs.
