FACTORY and Screamin’ Eagle cylinder heads for the Milwaukie 8 engines 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. This helps to prevent cylinder head cracking due to the more even distribution of that stress.
