The stage 4 VQ35 heads are for someone who has forced induction on their Nissan 350z or Infiniti G35 and wants ultimate HP and flow through the heads. If you are rebuilding your bottom end it is a good idea to get your heads refreshed. We have over 14+ years experience with Nissan/Infiniti motors and know what it takes to make power.
