I forgot about the AFRs. I'd put them at the top of that list, but figure on paying $1400. Also, some people have had problems with the rocker arm bolts being too long on the pedistal mount versions. The bolts are threading in all the way to the bottom of the pedistal, before the rocker is even set to zero lash. They might call for longer than stock pushrods.
