Yes, all four are different. What's being discussed is the ratio of the length of the short arm verses the long arm of them.

Greg,
Just checked the Dunstall tuning book. Page 17 does say rocker ratio 1.1 exhaust and 1.3 inlet. Either the factory manual or the Dunstall book is wrong or Dunstall used their own custom rockers.

Worth using in any motor with a skimmed head. Steve Maney sold most of his pushrods 0.090" shorter to cater for high lift cams and skimmed heads.
