A. Rocker Arm Pedestal Modication.
It will be necessary to mill a step in all six pedestals to the
specied amount. The step must be parallel (+/-.005 in.)
with the bottom of each rocker arm pedestal.
B. Rocker Arm Pedestal Head Stud
Installed Height.
If the location of the rocker arm pedestal
head studs are above the specied
installed height, it will be necessary to
tap the threads deeper in the block and/
or modify the thread counterbore to get
the top of the studs down to the specied
height. When installed properly the tops of
the rocker arm pedestal head studs should
be ush with or just slightly above the tops
of the nuts when the head is torqued to its
nal specication.
