The 4 (dot) to determine open verses closed head is a relevation to me.  This is an extremely beneficial data point as common understanding among many knowledgeable Pantera owners has been that it required intake removal at the least to see casting marks that could identify.

I have open and closed heads in storage that I will eventually inspect to confirm.  However before I make my way over there, can anyone else confirm the accuracy of this casting mark as an indicator of open verses closed combustion chambers on a 4V head?
