I am using Crane narrow body "gold race" rockers.  Note that while all <1988
heads may use a stamped version of a self aligning rocker arm, not all late
model heads really  require them.  My cast iron truck heads have a slot in the
cast iron, as opposed to a large hole.  I DO need the narrow body ( center bolt
valve covers).  For some reason Northern Auto Parts carries these at a lot less
($240 vs $300) than the self aligning type & if you moved up to a performance
head that used guide plates you still have the right type of rocker arm.
