That’s what you want. I just picked up a JDM K24a as well. Paid $850 which seemed fair for how complete it is. The head on mine is stamped RBB-3. in doing my research prior to my purchase there was some miss information that some RBB-2s and all RBB-3 heads were the same as the US 06-08 K24A2 with the updates. That does not seem to be the case as I measured the TB intake opening and it’s just over 60mm not the 64mm like the 06-08.
