I know the ratio is 9.5:1 but I'm trying to calculate a new compression ratio because i have a new block with dished pistons. Does anyone know how much CC the head holds

My slightly educated, albeit complete guess, would be between 50 and 55 cc; For memory the EJ207 are 55 as are the 257, but the 255s are 50.
Again, this is my complete guess based on other heads
