Feuling/ARP rocker arm shaft studs and nuts to help relieve stress on the Milwaukee Eight cylinder heads. The stock and Screamin' Eagle cylinder heads have an extremely weak link with the rocker arm shaft standoffs. By using a stud some of the stress is transferred from the standoff casting into the stud. The use of higher lift camshafts and heavier valve springs puts additional stress on the cylinder head, making the use of these stud kit a must in 2017 to present Milwaukee Eight engines.
