Default compression ratio of EJ257 with DOHC EJ25 heads

What would the compression ratio be of a EJ257 block with heads from a 98 DOHC EJ25. Would I need a thicker headgasket set since this engine will be used in conjunction with a beefy turbo set up? I already emailed Ron at Axis but he is away until Monday 04/24. Can anyone give me an idea?

Thanks, Jay K
