Ok so the chamber with no deck to speak of is a d jet 4.5. Meaning quite a gain for a d jet 4.5 with a 3.5 head. I'd be interested to see the cc on a d jet head. I do have one off an engine here. Not as much as I'd like on the k jet us motor. A euro d jet at 8.8 stock should really come up but not sure how much without head info.
