All heads require a core! Right now we are unable to effectively source good used cores, and we cannot get new cores from Mitsubishi.  You have to send your head in for porting.  Sorry for the inconvenience.

*If you are sending your head in for porting, please send your buckets and camshafts so that we can set lash*
