ggzilla Posted January 6, 2010 Report Share Posted January 6, 2010 I've seen dozens of A-series head, US, JDM, etc. And never seen one cast or stamped '68HP' or anywise similar. * H891 is likely the H89 JDM head for A14/A15. * Many of them say 612, meaning of which is unknown. Quote Link to comment
