The mystery is solved...

This is a 351c 4V closed chamber head.. or was

A former owner had 351 Boss pistons in the engine. In combination with the 351 closed chamber heads the comp.ratio become too high( >12:1???). It seems that the former owner modify the heads to OC style heads by grinding the chambers(black area in the chambers- see pic). This resulted in chambersize something in the middele of closed chamber and open chamber. Only a proper CC mesurement will give the answer.
