Ported 452 or Edelbrock RPM

Yeah, those are closed chambered, what is the piston flat to deck distance on Your slugs?
I don't remember but I measured it some time ago and my notes say it was just over 7cc capacity. I think minium safe distance is 0.035 and head gasket alone is 0.039 + I guess around 0.035 is the distance I have between piston and deck.
